Criminals can always get access to the things they want. They might borrow a car, whether the owner knows about it or not. They can buy a cheap car off of Craigslist. They can rent a Car2Go. Etc etc.
I find the "do you think this is the first time they drove drunk" argument to be unpersuasive. Every drunk driver had a first time that they drove drunk. I shouldn't lose my vehicle because someone got drunk after borrowing it.
I'm also sure that I have friends who have less than stellar events in their past but who have decided not to share that past with people. Some of my friends could even have a DWI. I don't know. I should not be required to run a full criminal background check every time I lend something to someone.
Now! All that said, I don't lend my car out, period. No one cares for and about that car the way I do, and so I try to keep the number of people getting their grubby mitts on it to as few as possible. But those who are more generous than me should not be punished just because someone borrowed their property and committed a crime with it, unless they knew the person intended to commit a crime with it.
Lend your car to the drunk at the bar? Sure, the car can be confiscated. Lend it to the minister next door who drives it to the bar and gets drunk, and then gets busted? Confiscating the car is not even close to justice.
