Re the original mention of tiny karts, small size is only a downside when it

So which roads are these lanes going to be on? Many of the roads around
here are barely wide enough for two vehicles.

yup, only workable where any of the following could grab a little space:
lanes wider than they need to be
more than 1 lane
pavement wider than needed
routes too narrow for cars
