The democratic law of the land. I don't like it any more than you do - I'm all for increased penalties when drivers kill people, and/or banning cars from city-center streets - but society functions when people follow the democratic process to change laws they disagree with rather than just breaking them.
Breaking laws is almost always the first stage of having them fixed. People can now see there is a demand for electric scooters and they need a safe way to ride them. Without riding them on the footpath there would never be any visible demand for them and everyone would just continue driving to work.
