Why are wasps so interested in cars?

It's that time of year again when the bloody paper wasps start buzzing around half dead. I hate these things with a passion.

One thing they tend to do around this time is develop a sudden fascination with cars. Went out this morning and there were a couple buzzing around mine. They seem most interested in the rad grill and the bottoms of the doors. What up with dat?

I did a quick Google but I didn't really get a straight answer. One said it's a sticky goo that falls from trees and another said it's the heat the car gives off. Though I've seen them do this with freshly cleaned cars, and in the morning when the car is still cool and hasn't been running for hours.

funny, august is the period where wasps become most active here, but when they die off, I never see them. I get a shitload of flies though.
I think they're looking for heat just like the other insects in autumn.

I'm guessing heat, possibly combined with color. I don't have a problem with paper wasps, it's yellowjackets that bother me. In September they're getting ready to die, and have a shitty attitude. They're in every trashcan, or stray food scrap, and will attack, cause fuck you.

You're lucky. When the wasps die off around here they come back as zombies, with an unquenchable hunger for human flesh. September is often referred to as "the plague of undead wasps of summer" here in the Pacific Northwest. But at least it distracts us from the rain.

It pisses me off when they build nests in/under various car parts. My expedition seemed to be particularly attractive...under the rear hatch, in the mirrors, inside the door frames, etc.

Yeah, they like my cars too. I dunno what's up with that. I do see them around the front grills, but sometimes just on the car. Never thought it was a thing, hmm.

had a huge nest in the mailbox, sprayed it with hornet & wasp spray late at night and ran like hell, found them all dead by morning, like 30 of them.

but OP is canadian.
Here the nights have gotten slightly cooler already (like 18°C), so in canada it might be already too cold for insects. If it's too cold for insects, it's not summer.

I always thought they were eating insect guts off the fronts of cars, but just being attracted to warm objects seems like a more reasonable explanation.

Maybe if you didn't have a pink car that looked like a giant flower.
