In the US city that I live in, cars get stolen an awful lot too. And not just puffers (cars left with the keys in the ignition to warm up on a cold day) -- I've heard of plenty of locked recent-year cars stolen from private locked garages with no keys at all. I believe car theft is up at least 500% from pre-covid.

And that's to say nothing of the opportunistic catalytic converter thefts if you park your car on the street overnight.

Most of these thefts utilize "relay attacks" that simulate the key being in close proximity to the car, using directional antennas to interrogate the key that's sitting in the house and then relay it back to the car. The solution is to disable the proximity feature, but that's inconvenient.

Where I live I'd guess the rate is 100 bikes stolen for every car.

With a bike you don't expect it to be there after locking it in the street for more than 15 minutes. I don't know anybody personally whose car was stolen.

In France, all bikes must now be marked to prevent theft https://www.bike-eu.com/laws-regulations/nieuws/2021/01/fran...

Is there similar plans in the US or at least some states?
