And when everyone adds enclosures i.e. ends up in a car, you’re at much more risk than you were before and have all the harms of car-centric urban planning.

The physical ability of people is historically specific and if people were to generally cycle most would be able to ‘operat[e] such a contraption’.

It is possible to regulate cycle lanes so that people don’t just zoom around irresponsibly. Curiously you don’t seem to consider equivalent risks from cars (can’t drivers act irresponsibly? is it preferable that they have several orders of magnitude more mass with which to injure people?)
