Bikes are great, I ride mine whenever I can. But most places lack secure bike parking and the police don't take bike theft seriously. So sometimes I drive my car even to places where I could easily ride a bike just because I'm confident the car will still be there when I get out.
Replacing the bike is actually a lot easier than getting the windows fixed IME.
If I can't find a good spot to actually lock up the bike though I will just bring it in to wherever I'm going. Shops or restaurants don't seem to care if a bike is parked in the corner and you can thread your ulock through the wheels and make it useless to ride off with.
This doesn't scale to wider bike adoption, though.
I think that's true at the moment, but only because there's so little demand for it. You can always find a sign post or something because no one else is snatching them up.
At the end of the day bikes are still private vehicles and, though they're smaller than cars, they aren't that small and the infrastructure to secure them (which is integrated into cars) isn't small either. So you get the same problem writ small.
Heck—if you have a car & your building doesn't have parking, you're basically screwed. If you have a bike & it doesn't have a bike rack, you can just carry it up & put it on your balcony. At that point, I don't think you can really compare the two.
