Is Level Four Autonomy Possible?

I'm definitely more bullish now after having ridden in it than I was before. These are still R&D platforms as they're trying to get this figured out. And eventually those sensors will shrink, they'll get less expensive and be more affordable for larger scale. But at the moment, I don't know how much one of those Waymul vehicles cost with that sensor package, but I'm sure it's pretty expensive.
