Just what you need for an long distance touring ride... plus a follow up car with trailer, loaded with spare charged batteries, a generator....?
Be prepared for an extended stop every hour or so to change/charge batteries...
Maybe strap a solar panel on your helmet?
Cant see any use for these outside of city area, and I am sure the boys in blue will approve of commuting at 350 kph on suburban streets ...
