I am now the owner of a Bolt EV. Why? Because I was at a stop light with my breaks applied in my Honda FIT EV and someone not paying attention slammed into me. Having my breaks on dampened the blow from my FIT EV to the car in front of me.
I would advise always using breaks when stopped. Even with Break lights you can get hit; but I dont even want to think about what would have happened if I didnt have my breaks on.
