The timing is the culprint here.
It looked like this when I published my 3-wheeler.

Here is my 3-wheeler...I also had 4 wheeler...which resembles more the Cyber Truck. See the sharp canopy...this is the essential part which is also in the 4-wheeler I had ( it was secret ). Now If I wanted to make the 4 wheeler...it would be consided copy of the Tesla Cyber Truck.
Yes I understand the problem with suspension...exactly that is the thing I have solved now in my newest design. I made one that Elon Musk's hench men copied as their Cyber Truck....but the vehicle itself was lame and flaved ( looks was good )...that is why I published it...3 months before Tesla...
Not necessasarily..Sun Seeker 1 travelled across US in 1991 with less efficient panels using 1,5 KW for a single a seater.
Some batteries would need to be...to get higher quickly.
