Honestly this is a good thing. There are too many big companies, not enough small, we need more to fail - esp the type that have gone through lots of mergers to reduce competition.
Smaller players would also be far less likely to enter less lucrative markets.
And unlike the big companies, there were no hidden costs, no upsells, no attempts to scam, no attempts to extort huge fees when trying to change the rental, ... didn't even charge us for forwarding a traffic ticket which would have totally been their right.
After my experience with Hertz (US) as a customer, the only reason why I'm not 100% happy with them going under is that I don't expect their large competitors to be much better, and less competition means the others can become even worse.
