While all true people also do not service their cars and these must be serviced on a regular interval with non standard components. Still a stupid design though which should never have been out into production. Glad my car has a chain, even had one in the past with a wonky guide which made lots of noise but worked until the end without issues (write-off was not engine related but purely economical, expensive tires brakes etc).

The wet timing belt reduces fuel consumption by about 1% so you can thank efficiency requirements for that.
