No, I don't think that's accurate. I just like to be "crisp" with my driving, if that makes sense. If there's a guy going 65 mph a 200 feet in front of me and I'm also going 65 mph, but I'd rather be 40 feet behind him instead of 200, I would rather not, say, speed up to 75, and then slowly feather my speed so that my speed slowly drifts 70, 69, 68, 67... and hits 65 precisely when I'm 40 feet behind him. I'd rather speed up to 75 until I'm 45-50 feet behind him and then quickly drop back down to 65 (obviously not by slamming on the brakes, but I'd just rather that the deceleration happen crisper and faster, but that the brake lights didn't blink on).
This seems to be worse on a downhill, where even a moderate 15 or 20 kW regen is not enough to slow down the car, and certainly not enough to slow down fast enough to make it easy to slide in and match speeds behind somebody at a given distance.
For example: I get into the fast lane to pass somebody, and accelerate so I'm not hogging the fast lane too long. You know what I mean: the guy in the middle lane is going 74 and I want to go 75, so I pass him on the left, but temporarily boost up to 80 so I'm not being a pest taking 45 seconds to pass one car. Then I get back in the middle lane and want to drop down to 75 again, but I don't want to scare the guy I just passed with a brake light - I'm just slowing down to a speed that's still faster than he's driving, but maybe I want to do it quickly, so I don't rear end the guy in front of me.
