It doesn't bother me too much in my Smart, I have got used to the ones you need to really slow for, but most are a little thump. Short wheelbase and narrow track is the problem.
Noticeable difference when im using the 5 series though.

If you drive regular routes, you usually remember what to do at each one

That said, I still hate watching cars come down my road acting like its a slalom to use the fastest and comfiest route over said cushions.
