Do people actually use their garages to park their cars anymore?

This may sound like a rant, but it's really not. I'm genuinely curious to see if people with garages actually use their garages for storage or for parking.

I do delivery work, and so many streets are just packed on both sides with cars lined up end to end. It's awful on the streets with rear garages especially. There's barely enough room to fit one car let alone 2 in opposite directions and no where to pull over to let the other go by.

But the other day during the snowstorm I found a spot and pulled in so I could deliver my items, and I didn't get 6 steps before some guy pulled up and demanded I get out of "his spot".
