Why would they focus on "cybercab" over this. Everything that makes the cybercab cool will never be legal in a consumer product. Cybertruck is definitely more useful to an average person.

An average person has no use for a truck that costs more than twice what an average person makes in a year and half or more what an average person spends on an average house

the economics of Tesla , a company with lots of capital, renting out their fleet make more sense in a market of consumers with little disposable income.
