VC: Not enough startups are building self-driving car software
Venture capitalist Reilly Brennan believes that self-driving cars are coming faster than most people expect, but that the market doesn't have the best mix of startups yet.
Too much: Companies selling dongles for car data. "There are a hundred of those and there should probably be three," says Brennan, who last year co-founded transportation-focused Trucks Venture Capital. There are also too many "Uber for freight" companies, he adds.
