The hard part is convincing enough capitalists to invest into a high volume low margin product/company that doesn't have a real chance of being a jackpot win down the road. Investors don't want stocks that at its best gain a percentage or two above the overall market, there are plenty of other options with similar returns that have better worst-case results if there is a market crash. A co-op business could theoretically do it and would be happy with such margins, except it is unlikely a co-op is going to have enough capital to start with enough scale to actually push into the automotive market.
