I'd love to see new car manufacturers doing new things and appealing to different segments of the market, but I imagine there's so much barrier to entry, so many regulations to adhere to, that as a new car manufacturer it'd be near impossible to do anything new/different at this point, unless you're ready to throw billions into it; and even then, the regulations/laws are extensive enough that you'd end up making something 98% the same as what already existed.
