people who insist on going full speed and then SLAMMING their brakes drive me to drink, and this applies to literally all modes of transport.
If you’re walking through a grocery store and are about to round a corner, fucking slow down so you have time to see anyone else coming your way, then you can speed up again when you know the coast is clear.
If you’re driving a car and coming up to a red light, or even worse a pedestrian on a crossing, FUCKING SLOW DOWN and just coast slowly, it’s not worth the off chance that you get to blast through at full speed, not for you or anyone else.
