You realize speed bumps are not there to 'ruin driving'--they are mechanical means to stop drivers from speeding as signs are useless and as soon as people are past the cops they speed again.
Let's say they're put there even though they ruin driving for regular people, because they will also stop the few speeders. I don't really speed, but I take a speed bump as a sign someone in the neighborhood is hostile to drivers.
I lived in this neighborhood, on a dead-end street. They grew a new subdivision, and put the street through. Now we had people blowing through our neighborhood at non-neighborhood-driving speeds, trying to race between major roads faster than the major roads would take them.
We petitioned to put speed bumps in. Yes, we were hostile to the way at least some people were driving. But also note that we, the people who asked for the bumps, also drove there every day. We weren't hostile to drivers as a class. We were hostile to people trying to drive excessive speeds on suburban side streets.
