I had something similar, although simpler: it's called a velomobile ( https://en.wikipedia.org/wiki/Velomobile ). It's a bike but with some added aerodynamics. You can easily ride at 40km/hour (~24mi) only with your muscles. It was very nice to drive: very stable and rather fast and i did 2x20km/day to work. However its bigger weight compared to a simple bicycle makes it not suitable to mountains

I would love to buy one and do some nice trips in the Italian back country. Problem is, it's very hard to understand which model(s) are well designed, and also hard to understand where to buy it to get the best price.

Is there any recommendation you could provide?

Another example of how, if you had to design a vehicle for passenger city/suburban use, you would never ever ever come up with an ICE sedan, or to be honest even an electrical vehicle of "normal" proportions.

Pretty sure the car is the most harmful invention of the 20th century. The damage it has done to the environment, our health, and social fabric is hard to grok.

A couple edits for clarification:

- I'm talking about using cars to transport individuals to work, school, lunch, errands, etc

- Cars are very harmful to health. Most obviously, they kill a lot of people. There's over one million road deaths worldwide per year[0]. (Covid killed 4M). Less obviously, they are terrible for health. Living next to busy roadways is linked to increased dementia and other neurodegenerative diseases. This has nothing to do with CO2--it's the rubber and metal and not addressed by Teslas or whatever.

- Cars make people dumber. Students who move to schools downwind of busy roads have lower test scores [1].

- Less obvious is the damage to social fabric. It's not just a distance thing: it's an estrangement thing. People in cars skip the places they move through as opposed to inhabiting them. Think about some busy thoroughfare at night near your home. Does it feel safe?

- Think about Houston. Think about Mumbai. Think about Lagos.

- Getting rid of cars does not mean everyone has to use public transport. In fact that was my point. You can design a vehicle that takes you quickly from a -> b that doesn't weigh 2 tons and uses 18m^2 at rest.

- Getting rid of cars does not mean getting rid of ambulances ffs.

But my main issue isn't how bad this all is: it's how unnecessary it is. As a species we are more than capable (as evidenced by the OP!) of building a variety of modes of transport that are better in most every way (utility, externalities, price) to cars.

Driving them feels like sitting in a space ship.

Source: I've driven one for a couple of minutes once a couple of years ago. In Switzerland they are kept alive and running by a number of enthusiasts.

Interesting but extraordinarily expensive. I assume current battery tech, etc. should provide a much lower price.

These are awesome, but they are too small (and too slow) for the road and too big for the bike path or sidewalk. I ride a scooter to work everyday. (Inokim Ox). Its legal on the sidewalk where I live. I really think scooters are the future.

Agree, Twikes combine the disadvantages of both. Its more the expression of an identity instead of a rational decision.

There is a similar four wheeled HEHV being produced in Norway: https://www.podbike.com

Wow, the hoops you have to jump through to find a price!

5k or 5.5k, depending on variant.

Although to be practicable (not a hobby), you will have to add quite a few "extras".

But not that bad actually! Makes me wonder how it is built.

I've had to do all of those things, and still agree that towns and cities being designed with cars as the default mode of transport is insane
