They could spend $75/hr on employees and the cost per car-hour would be just $1.50. That's nothing.
3.5M people work as truck drivers in the US, enough, in principle, to drive ~175M cars at the same time assuming 2% of cars need help at any given moment, ie ~60% of all the cars and trucks in the entire country being driven simultaneously.
Presumably though they'd be able to shave that down a few fold between where they are and dominating transportation nationwide (should they ever do so). So, it's pretty scalable in practical terms.
This is true, but the numbers inflated even. There's no way they'll pay these people more than $15 or $20 an hour once it scales, which probably further helps your point.
