I hated Tesla Auto before it was cool

[Disaffected]

1. Whatever one may think of Musk and Tesla,

your criticism of the first Falcon Heavy (with the Tesla roadster as cargo) a little off-base. As it was the maiden (test) launch, it is not unusual to carry a deadweight payload of low value. The launch would have been necessary whether or not the deadweight was just that or, the roadster prototype that was utilized in that case for publicity purposes.

In any case, the launch was a notable technology accomplishment and demonstrated the practicality of triple booster reusability.

Also, I'm not sure what you are referring to by "solar electric vehicle" unless you mean a conventional vehicle that is recharged by detached solar panels i.e. electric vehicles that are charged by solar panels mounted on the vehicle itself are not now practical as the driving range is very low (not enough space for the panels).
