"When you do need to do a big evacuation a Tesla sized battery can last longer than you can safely drive"

This is plainly wrong. Let's say it's a Tesla Model S which has a real world range of about 400 km. That is about four hours of driving. I sometimes drive 600 km easily, with one longer break to eat and maybe a few shorters breaks to pee or just get out of the car and walk around a bit.

Your other statements are also somewhat exaggerated, see for example: https://insideevs.com/exclusive-interview-with-steve-marsh-a...

The EU legal limit is

> a break or breaks totalling at least 45 minutes after no more than 4 hours 30 minutes driving

and

> 9 hours in a day - this can be extended to 10 hours twice a week

https://www.gov.uk/drivers-hours/eu-rules

The range of a 100KWh model S on the page for the UK ranges from 319 miles at 70mph (four and a half hours) to 514 miles at 45mph (eleven and a half hours). At 100KWh and 3+ miles per KWh (https://forums.tesla.com/forum/forums/real-world-range-new-o...) that's still 330 miles, plus.

Certainly seems like a reasonable claim that the battery can last longer than you can safely drive, particularly if you're not gunning it down a nice fast road.

Yep, on evacuation day, when you are sitting in stop and go traffic, EVs are a big win because they get much better mileage at low speeds.

Wow. A 6 or 7 year old car that is completely useless. A 3 hour charge time to go 65 miles. If it's highway driving - only 35 miles - unless there is a headwind.

Mind boggling.

That's not all:

  > No more regenerative braking
  > 35 mile range now
  > Using the QC (quick charger?) more than once a day voids battery warranty
