A toy-sized tear drop with barley enough room to fit a person in it, and the safety profile of a soapbox car is only 80(x?) more efficient than a full-sized EV?

A toy-sized tear drop with barley enough room to fit a person in it, and the safety profile of a soapbox car is only 80(x?) more efficient than a full-sized EV? That is surprising.

it is enough for 1 person, and plenty of bags around :) also, 450km range when used with 2 more batteries (only 6kg) 80 times more efficient

  Is there a breakdown of the human-supplied vs battery-supplied energy for 450km range. Is this going down hill, uphill? How much cargo? "Plenty of bags", what type, plastic lunch bags filled with air? In the "80x" more efficient, does it just count human calories as free, because I don't think human calories are as green as you think they are. Let's say I want to do something actually useful, like grocery shop, and I need 30kg of groceries taking up something like .3 m2 space. Where does this vehicle fit into that use case? Also, I want to not die if I impact anything more substantial then a tumbleweed. It's pretty annoying when people put forward a totally unpractical solution then throw their hands up with a "well we had the solution that could save the world but nobody listened!"

    There is whole youtube channel for someone who regularly rides one to go to work, so I guess that's practical enough for him. He is still alive too. https://www.youtube.com/@TheVelomobileChannel https://www.youtube.com/@TheVelomobileChannel, and specifically the video about luggage space and other things https://www.youtube.com/watch?v=o1bU5SIVq6k https://www.youtube.com/watch?v=o1bU5SIVq6k. Note that he is using full leg-powered velomobile, not even electric one > does it just count human calories as free Are we really also gonna include the fact that exercising reduce medical bills in long run?

      Oh, well if it works for one guy on the internet for his use case, it must great for everybody and everything then. > Are we really also gonna include the fact that exercising reduce medical bills in long run? Are you really going to suggest that riding a death trap tin can is an intelligent way to reduce medical bills? Thanks, I'll just do my calisthenics and cardio at home, 100% death-free.

        Great! Glad you recognized the fact it can have some valid usecases
