This would be the last time I used that rental car company. If they wanted to make more money from you, they should have just raised the price. That is disgusting.
New Zealand had a service called YourDrive[1] that was pitched exactly as "AirBnB for cars"[2]. I used it a couple of times and it was great, super affordable. Unfortunately they didn't survive the Covid crunch.
Thanks for the link. I once again find myself in that exceedingly strange zone where satire and reality become undifferentiable and I begin questioning my understanding of the world.
