Even "slow" teslas are fast, comparatively speaking, in almost all the ways a regular driver would identify "fast". Off the line, 20-70, etc. With that being said, even cars that might be faster than a model 3 performance (say from 30-90 or something) usually arent in a practical sense, because they have to downshift, etc.
The instant torque + lack of shifting end up re defining what most people think of when they think "fast". Its also the fastest car I know that is also "completely happy / fine" with also driving slow. Most fast cars seem to beg to be driven fast. If they have adjustable modes (like comfort or eco + sport. for example) when driven in eco mode they feel like econobox cars, no matter how much you spent on it. Driven in sport, they feel more like performance cars, with the hit to gas mileage that entails.
My BMW 435 got about 17 miles to the gallon, because I drove it in sport mode all the time, but that was really for the throttle mapping only. The car felt completely unresponsive to me when driven in "comfort" mode from a throttle response standpoint. So, even though the car was rated at like 26 mpg I think, in order for it to even feel close to being a sporty car I had to use the sport mode, even when I was just sort of cruising around.
The model 3 scratches both of those itches for me. 90% of the time I am cruising around. My lifetime wh/mi on a model 3 P with 27k miles on it is 269 wh/mi, so that tells you I am definitely cruising around most of the time, lol. When I want to, however, just a press of the accelerator pedal, and "im gone". I almost never floor it, either, unless I am showing the car to someone. The reaction is always the same for someone who has never ridden in one before.
I say "ill take you for a ride around the block".. we get in the car, I cruise around the block to a spot where we have a 4 lane highway close to my house, say, "ok, hang on", they look at me kind of puzzled, I floor it, their eyes bulge out of their head and they say some form of "Ohhhh shhhhhhhhh". 2-3 seconds is all, I let off the pedal, and they all get this look of "wonder" in their eyes.
Then I tell them, "it cost similar money to the BMW M3 I was going to buy, but my commute costs to work are about 50% less than that would have been, and I havent been to a gas station in 2 years, its like having a gas pump in your garage".
(there is a reason i am rolling around on Zero G referral wheels, lol).
