The problem of drinking and driving is real, and well asserted. But since alcohol is entrenched in our society, and in America most places we simply suck at public transportation, we have this problem. If you go out somewhere and consume alcohol to drunk, or if you sit home and get drunk and decide to go buy another six pack, you have weaponized your vehicle, but that wasn't why you have one in the first place. And you hear people yell and scream when a drunk driver hits and kills someone. Simply murder, it was! Just as if they'd taken a loaded gun and shot someone with it. It's obviously not the car's problem, it's the driver's problem. Obviously the alcohol inside the person (by choice or due to the disease of alcoholism/addiction) is the problem, not the blooming car. Very poor argument that guns=cars. Because it just doesn't hold up. And when you take someone's vehicle, in this society, you take their employability, their self sufficiency, their family's transportation in many cases. That's not something you do on a one off, with no second chances. One doesn't have to have a gun to get to work. One doesn't have to have a gun to get around. Yes, it should be different, we could help the problem of drinking and driving, we could simply confiscate the car of anyone caught drinking and driving forever if we were a completely different country, with a well developed public transportation and bicycling and walking culture. But we aren't.
