Is it possible to imagine a scenario in which this would be a problem? Yes, but it's virtually the same as with seatbelt laws in that the hypothetical problems are disproportionately outweighed by the benefits (and by a few orders of magnitude at that).

My least popular (and most correct) view is that cars should be automatically limited to the local speed limit. Put the pedal to the floor and you still can't go over 25mph in a residential area.

There is no possible justification for limiting e-bikes to 15mph but not cars.

Statt jetzt wieder 3 Tage über einen offensichtlich onkelig-dummen Satz von Merz zu diskutieren, könnten wir auch darüber sprechen, dass er als deutscher Bundeskanzler kimapolitisch blank zur Weltklimakonferenz gefahren ist, wo gerade über den globalen Ausstieg aus fossilen Energien verhandelt wird.

The much sader version of the Groucho Marx adage "I refuse to join any club that would have me as a member"
samthielman.com CHOAM for the holidays @samthielman.com · Nov 11
“whatever club he’s invited to join has been devalued by the invitation”
Tweet by Joyce Carol Oates: "wherever he goes, he wants to leave"--that's because when he gets there, he has brought his own self along; & whatever club he's invited to join has been devalued by the invitation. QT of @avidreader1000 Wherever he goes, he wants to leave: SA, Canada, ultimately the U.S. in the long run, based on his behavior. This also includes Earth.
