Well my personal negativity is partly based on a feeling that his products are clever, quite well engineered but seriously over priced. He is a businessman/technician who has worked out a successful formula for persuading people to pay 10 x the price for something marginally better than its competition. That in itself is not a 'bad' thing - but it's more akin to the genius of Gucci and Armani than the genius of Gugliemo Marconi or Henry Ford. Couple that with his 'I'm all for Brexit' because British, while manufacturing in Malaysia.
In his favour - he believes in R&D, and he appears to recognise the social benefit in taxation. Good luck to him with his electrical car.
