And in Austria you need a reflective vest for every passenger. And if this wasn't silly enough, then in Russia and Ukraine, as I suspect in most ex-Soviet countries, also a fire extinguisher. In the Czech Republic a year or so ago they changed the requirements for the first aid kit, thus screwing anyone who didn't buy the new version. Cops love to check all of this too if they're bored or aren't reaching their quotas otherwise, so be prepared to unload everything from the trunk to demonstrate that you do, in fact, have all of this crap.
Shit's getting ridiculous, really, soon I'll be going for Sunday drives with a surgeon riding shotgun, just in case.
