Sure, but it is still creepy anyway. I have no issue with the services provided here, just wouldn’t let some stranger know we were leaving an empty house for a while.
If the driver in question had simply notified someone else to do the robbery, he may have gotten away with it.
It’s no worse a threat than getting an airport shuttle or taking a conventional taxi. The latter has been a threat for two hundred years. Are you equally concerned about that?
As for the latter - if he had texted, the text message could have been available to law enforcement. Same thing if he had called using his phone.
