I've struggled with similar issues before - when travelling, or out in a city, where to do some quiet work, or take a call, or speak to a group of colleagues?
I've explored short-term (i.e. hourly) office space rentals, but IME the low headline rates ("from...") become a lot higher when you dig into the specifics and have minimum spends. I'd happily pay $<=20-30 for a convenient small quiet office for an hour, but not $80+. I've also never found a service that offers anything like the low friction that (from the article) unlocking a car remotely would offer.
I wonder if this area is ready for some disruption...?
