>A Tesla will out accelerate all but the most niche cars now.

Claims presented without evidence. My slightly modified Subaru Wagon from '05 "out-accelerated" base Teslas - dead even in 1st gear, started pulling once the shift to 2nd happened. (Most) EVs cannot shift gears to get torque multiplication, so they start fast, but fall off as speeds get higher. My Kia gas car will outrun all but the model 3 performance - which the average person is NOT driving. Neither of those cars are "niche".

Slightly modified is doing some heavy lifting there. No 2005 Subaru wagon in stock config is anywhere close to beating a Model 3.

Pretty much irrelevant, because they’re still blisteringly fast up to 60 which is where most of the acceleration happens in day to day. Nobody really cares about 60-80 or 60-100.

What Kia is that? Even the stinger GT (which is definitely a niche car) is slower than a regular dual motor model 3.

EV motors can rev insanely high, so they don't need to shift gears, while most gas engines are limited to 6-7k RPM from factory. Thus the gassers need gears that essentially torque divide to reduce RPMs. You are very confused.

This doesn't make any sense. You can do a < 5 second 0-60 in your Subaru or Kia?
