There is one already on the roads around here, and it does not seem to inhibit traffic around here.
It goes 2 1/2 times faster than my electric scooter and has a roof for those days of rainshine.
The roof is a 100 watt solar panel that can recharge the battery in one day, or I can plug in a charger
like I do for my mobility scooter. It needs no insurance, no license plate or drivers license.
Roads around here have wide shoulders for bicycle traffic, so it is no wider than the three wheel recumbent
trike I used to have and is much more visible. Most drivers here, at least the non tourist ones, are more considerate
of others on the road whether they are in cars, on motorcycles, or bikes, than anywhere else I have lived.
Maybe somewhat less so in Kona or Hilo, but I won't be riding it there. Furthermore since it has bicycle assist pedals
It may give me some needed leg exercise. I can't ride a bicycle because my feet fall off the pedals.
