Why do people fit those bonnet covers? Stone chips?
I’m reliably informed by an American friend that it’s called a “car bra.” Srsly.
They’re really prevalent in the US. I think it’s supposed to be to guard against stone chips or dead bugs or something, though quite why the front few inches of your bonnet is more in need of protection than the skirt or any other part of the front of the car, I have no idea.
I suspect that mostly, it’s a solution to a non-existent problem, bought on the assumption that if they’re selling them then I must need one.
