Definitely, if they were legal in the countries where those tinkerers live. I can see replacement electronics and batteries and motors being done to try to extend range and improve performance. The use of commodity rather than special automotive parts is not a problem - most experimental electric vehicles (include e-bikes, skateboards, etc) don't use automotive specific parts, because those are usually too expensive, too specific purpose, and occasionally proprietary. If these cars were sold with schematics or even block diagrams I could see lots of people buying one just for local use or modding.
