It depends on how you prioritze the numerous downsides - - safety (collide with a Harley and it’s about a tie), cargo space (picking up cement and lumber at Lowe’s?), and passenger capacity and leg room. My primary concern would be safety. I simply would not want my wife or one of my kids driving around in something that small.
Oh, not going to REPLACE this with my car/truck - for exactly the reasons you list. But for 65mph drives on a freeway to/from work - it’s pretty attractive. And with 3 airbags, a composite body and steel frame and more crumple zone than other vehicles in it’s class - it’s not that bad. We will see, but they are anticipating a 5-Star Safety rating; which is as good as it gets.
But, at it’s price point and 84mpg it’s a reasonable commuter vehicle; which I believe is it’s intent.
