I will usually put my (electronic) parking brake on when stopped at lights. I havent actually checked the brake lights go out…
Means I ca npull away just by pressing the accelerator. Unlike using the shifter (or a button) to go into P, as that generally requires you to put your foot back on the brake pedal to get it back in D.*
Unwillingly I have an automatic now, I guess this is why the majority of people are now just sitting on the brake pedal. While I like the automatic as a whole, it is most annoying in slow/stop start traffic. I would actually prefer a manual in these situations.
*even worse on cars that have the traditional PRNDL layout, going from P to D takes you through R, briefly flashing the reversing lights. Not conducive to the the car(s) behind you moving off efficiently when the lights go green.
