I mean, it’s right there on the name

is there arbitrage ?

1. order waymo,
2. open door,
3. cancel ride (pay cancel fee $4.99 ???),
4. pick up doordash order,
5. earn $6.25 ???
6. profit $1.25
   repeat

the man working for the machine and not the opposite

Seems pretty reasonable. I'm sure Waymo would much rather have a way to close them remotely, but that means a lot of moving parts to maintain and break if they fix. Since most people probably do close the door behind them, the marginal cost of paying a Door Dash fee for the occasional open door probably works out cheaper than retrofitting and maintaining door controllers on the entire fleet.

I think we just found the stimulus package for the economy!
