I don't see why this isn't the case with other people. With GetAround, the whole premise is that you're borrowing your neighbor's car, not getting a late model Prius from Enterprise that has been beaten to hell and back already.
When an AirBNB listing looks like they expect me to put myself at extra inconvenience, I don't bother with it. Especially with how many of them are basically full-time landlords of their rented spaces these days.
Now I understand AirBNB et al would love for folks to get suckered into the idea they need to pay cash and get the friend-loaned-you-something treatment, but that's silly.
Yes, money changes hands - you pay for use and cleaning of the place - but my Airbnb rentals have been significantly more intimate than any commercial hotel I've stayed in (even small hotels or regular commercial BnBs).
The notion that you'd experience any kind of "community" or "sharing" with AirBnB has always seemed like pure marketing BS. It's cool that you've actually experienced it. Maybe it does happen sometimes.
My wife made the Airbnb reservations, and she really likes meeting local people, so she may have selected for that experience.
It worked out really well for us.
How is it different from an ordinary rental car?
