The #APTERA will be able to accelerate from 0 to 100 km/h very fast due to its overall light weight and in-wheel motors. The opposite would also be true: The #APTERA will be able to decellerate from 100 to 0 km/h very fast or have a extremely small stopping distance due to its overall light weight and in-wheel motors regenerative braking. I think much faster than what the driver behind it in a heavy weight vehicle would be able to anticipate.
This is also the reason why you should never pass a 16 wheeler truck with a full load unless the road in front is clear - if you cut into the front and then have to stop or decelerate due to traffic you WILL get rear-ended! While your car will be able to stop within 25 meters that heavy load behind you will need at least 50 to 75 meters even if they are driving slower than you.
For this reason #APTERA should consider installing an early brake/decelerate warning system that is activated every time the #APTERA decelerate. Such a system already exist for motorbikes but in my opinion a bit costly at $90.
Smart Brake Module uses accelerometer and motion detection sensors combined with a proprietary algorithm to detect engine-braking or down-shifting.
It’s an intelligent system that doesn’t interfere with the actual brake light operation.
It simply senses when the bike is slowing down and operates the brake light in the situations when you’re not actually applying the brake.

Rapid flash on braking: NO, thanks!
Decelerometer based flash: YES, PLEASE!.....:
I was in stop&go traffic behind an SUV with a very bright eye-level LED brakelight repeatedly flashing rapidly EVERY time they had to start braking again, which was VERY frequently in that pretty common traffic situation. It was SO irritating that I went out of my way to get out from behind them.
HOWEVER, several times I've been behind motorbikes with the variable-speed decelerometer-based flashing, & it was actually very nice to be able to tell how hard they were braking.
