For the budget minded, the Honda 2022 Navi. 109cc, single cylinder, automatic CVT transmission - no clutch, no neutral, just twist the throttle and go. EPA mileage is 110 mpg. That black thing where the engine is normally located is a removable storage container.

MSRP of $1,807 + $200 destination charge. (Street price for the seven to be available in the entire USA is estimated at around $4500... whistle )
