I just park. If the space is really small and I need to bump to get in, then I bump.
I’ve parked and had less than an inch on either side. You can’t do that without bumping bec your car is longer diagonal than it is straight.
I did that by a fancy car that had parked in two spots so he wouldn’t get bumped. Then I moved my car bec I was afraid he would slash my tires. So I had to bump bump bump again. I really wanted to leave a note so he’d know what I had done.
Once upon a time I parked like that by a not fancy car, and when I came back the guy was there in his car, and he was an old frum man, and he called me over to yell at me, and I went over and said oh I’m so sorry and then we shmoozed for 2.5 hours. Really. He landed in Normandy. He told me so.
