Base model Leaf or Electric Smart? You’ll still get cruise control (you don’t need to use it), ABS (proven to save lives, but you can of course pump the brakes if you wish) etc.
Granted the Electric Smart is "only" $23K, but you have to look at the overall value (e.g. depreciation, utility, battery aging). I'd prefer to pay $27K for a plug-in Prius Prime (up to 25 mile electric, then gas).
