The nondescriptness of silver cars is a pro and a con - when I first switched to driving one there was an immediate increase in the amount of time it seemed to take for other drivers/pedestrians/etc to notice me, and I've had to adjust my standard of driving defensively to compensate.
Oh, I thought it was just me. I’ve come much closer to getting into accidents with gray cars, because I just didn’t notice them at a glance, or see the movement. Silver seems like a good color if you want to drive a getaway car, and a bad color if you have kids.
It's been studied, there is a crash risk increase for gray cars amongst other colours. I am on my phone and can't find am easy to access source except this:
I wonder if that's also true for scooter and motorcycles. I'm thinking about getting one of those, but ideally in some bright and highly visible color.
I imagine so, but I think you get more mileage from reflective high vis clothing.
Make sure you get to an MSF course, they teach you about lane positioning for visibility and defensive riding techniques. Some assume this means riding like Tom Cruise, but most saftey occurs by never being in an incident at all.
