I don\'t know how the traction control actually works, I just know I\'ve never been able to make the car go squirrelly, even if I want to. I\'m accustomed to being able to put a car or truck into a four wheel drift on ramps. I think I did that once with the Tesla, but it was very hard to do and I won\'t be trying it again. You really have to hit the ramp fast and hard. With the very low center of gravity it is amazingly well behaved on the road. Body roll is essentially gone.

Yeah the times it\'s occurred it\'s so fast I don\'t even notice if the TC

No I can\'t make the Volt get out from under me or do anything very
unpredictable with the TC on doing tests reasonable to do on public
thoroughfares like trying to make it drift into an empty parking lot on
packed snow at reasonable speed, where there\'s no great hazard if it
doesn\'t recover well, the TC is like \"no you can\'t do that\" and the car
stays pointed more-or-less where I point it.
I don\'t do unreasonable tests because I don\'t have a track membership or
anywhere to really fling it around in private. The TC and ABS have saved
my butt in real-world driving on a couple occasions but the TC lamp
almost never comes on when I\'m not trying to make it do so like above on
packed snow, if it does it usually means I done fucked up.
On some older GM cars when you turned the TC off it was really off. On
newer cars in general the Volt included it\'s never really off when it\'s
\"off\" it just switches to some less-aggressive control law.
The first gen was apparently more like the old days with the TC off but
the second gen is tuned by Bosch, zee Germans don\'t do do zis it is
alvays in zee control.

Well, yeah, if it is only full engine braking with no control, that would suck. The Tesla gives you continuous control over engine braking and engine acceleration with the same movement of the accelerator, one continuous control. It\'s actually excellent and is one of the things that make driving the car so pleasurable. That and the autopilot.
I think you have to expect that. If the wheels lose grip on the road any braking isn\'t going to work smoothly. I\'ve noticed that in ICE vehicles.
I don\'t even know how to turn TC off in the Tesla, but I\'m sure there\'s a setting for it. I\'ve never wanted to do that although I used to take my pickup into snowed parking lots to do donuts and would not mind trying it with the Tesla.

50mph is slower than HGVs speed limit in the inside lane and so really

Near the range limit of the vehicle you may not have any choice if you
are to reach the next working charger.
However, the vehicle must have the aerodynamics of a brick if there is a
noticeable range difference between 40mph and 50mph. I only see
significant drag affecting fuel economy at 55+. I guess resistive losses
hurt an EV more but I\'m surprised that it is quite so bad!
The *big* problem in the UK is that there are plenty of non working

The supercharging hubs they have built are unable to get supply so are

At the very least, if you\'re driving significantly slower than the
general flow of traffic, you should have your hazard flashers on.
Otherwise, you\'re at a higher risk of being rear-ended by a
less-than-attentive driver.

Even that may not be legal. Here in California, the Vehicle Code says
\"No person shall drive or operate on a highway at such a slow speed as
to impede or block the normal reasonable movement of traffic, unless
the reduced speed is necessary for safe operation because of a grade,
or compliance in the law.\"

So, driving slowly (and impeding other drivers), because you don\'t
want to run down your battery, is a violation, and you can be ticketed
for it. If you ignore the angry drivers and the police, you may end up
needing to explain the case to a judge, in court.

UK you need to know the rules as \"derestricted\" is a white disk with a

I can see that the lower the battery discharge rate the longer it will
last but the drag coefficient of the vehicle must be insanely high for
that to matter at such low speeds. It makes very good sense to limit
acceleration when the battery is on its last legs but the vehicle should
be able to do a bit more than 25mph without taking too much of a hit.
Once it is rolling you merely have to replace the energy lost to
friction and drag to maintain a given speed. Drag forces scale with
velocity squared so it seems very conservative to limit to 25mph.
I don\'t doubt that <25mph absolutely maximises the remaining vehicle
range on low battery if you live long enough to actually get there.
So non-functional public chargers is an issue in the US too?

I think the strength of the braking is limited by the amount you can charge the battery which varies. That\'s another reason to not charge up to 100% because much above 90% the regen is very weak.
I was driving the Kia today and while I don\'t dislike it, it does make me miss the feel of the Tesla. I certainly hope other EV makers are able to provide that same aspect of the Tesla experience. It\'s like no other car I\'ve ever driven, although I\'ve not driven other EVs.
I literally don\'t have the time as every update would require a reread.

The article talks about \"legal agreements\" rather than actual access to the grid. You make it sound as if they simply don\'t have a grid for them to connect to. Do you have more details on just what the issue is?
I\'ve seen no small number of Tesla Superchargers held up after all the work is done because new requirements were added by the inspectors. In one case that had dragged on for months the last issue pointed out after everything else had been failed and fixed... one at a time... was about stickers that explained the emergency disconnect was on a different level of the parking deck.

It\'s not a matter of efficiency, it\'s an issue of damage to the battery. They have to monitor each cell to make sure they are not being discharged below zero. This is at the very end of the battery capacity. I think in the Tesla this happens when you are below a couple of percent. One guy took his car down to I think it was 13 mile range trying to reach the charger and pulled over for some reason. He was videoing the dash and while sitting it went from 13 miles to 0 miles. I think the guy had an inkling this would happen as he doesn\'t video the dash by default and had no reason to pull over as I recall. Most likely this was the car renormalizing at the low end. It also needs to do this on occasion on the high end to have an accurate range estimate.
As to the non-working chargers, I\'ve only ever seen an individual failed charger at Tesla sites. Never seen a site down.

Up to about 40 mph the only thing the car has to overcome is rolling
resistance, especially if it has a low cd / sleek design body. Up
above that wind resistance plays a bigger factor even on the sleek
models. It does not matter what the drivetrain power source is.

Cali is friggin weird. They don\'t write a speeding ticket. They
write you up for \"too fast for conditions\" and that way it matters not
what the posted speed is. And if it is too fast you could eat a
reckless operation criminal charge.
The speed limit represents an UPPER limit in most places. In many if
not most. In today\'s \'idiots in a hurry\' world, even traveling at the
speed limit you end up with idiots crawling up your ass, acting like
you are holding them up. Driving in town like they are on a highway.

It wouldn\'t surprise me if it had been constructed where space

for EVs to make sense (but almost zero electricity generating capacity).
In the North I would have to drive around 50 miles (a long way in the
UK) to my nearest public supercharger. The physically nearest private
one is about 5 miles away at a very high end country house hotel. Snag
is they expect you to dine there and stay the night to have use of it.
Rural mains is nowhere near the capacity needed to handle everyone with
a nightly 7kW load. Several larger farms and businesses around me have
their own diesel generator kit because the local network cannot supply
all of the electricity they need to operate at some times of year.

Basically in London and the SE there is enough physical infrastructure
for EVs to make sense (but almost zero electricity generating capacity).
