The European Union has a regulation that requires EVs to illuminate their brake lights anytime the regenerative-braking system’s deceleration rate exceeds 1.3 meters per second squared, or about 0.13 g.

Cool. How did you know this incredibly specific value? Assuming that it is correct, how was it determined? I would like to learn more.

Simply because I've been driving TVs for a while and "in the beginning" when there was no rules for brake lights to be turned on when regenerative breaking, I got into trouble (German highways) with cars driving behind me and not being able to anticipate / react fast enough when I used it.

I quickly learned to force the break lights and started to follow this issue closely. That's how I became aware of the number.

How the EU saddled for 1.3 and not 1.2 or 1.4 is beyond my knowledge.
