Life gets more and more difficult for anyone trying to break into the car industry .... modern cars are just too competent and fast ... when the likes of Lotus and TVR broke they were able to do so with cars that gave a clear performance advantage over your average banger. Now your average banger has performance beyond what can be used to the full either legally or sensibly on the public road. Likewise earlier startups that were actually reliable at a time when most cars were often marginal in actually chugging up the road for the required journey could earn a place in the market.
Modern cars are just too good in general to make competition from a standing start likely
