I'm not sure I get your valuation model. "we're" not investing in self driving it's the car companies, because (presumably) they believe that self driving will make their cars more sellable compared with other brands.

If after another $50B or $100B spent some companies start to pull back on funding because they think diverting funds to other areas will give a better return (better batteries, cheaper manufacturing etc), it's likely others will too.
