Ah, yes, DB: I am aware of their reputation and, sadly, they also run some services in the UK where reliability and timeliness of service is also already shaky enough without their further assistance.
I favour public transport when possible, but until goverments create reliable infrastructures that go beyond the lucky ones able to afford rents in city centers within the radius of good transport connections, or not having to go by bycicle to work while collecting km/miles as training for The Tour, most folks will go with the car option.
You have my sympathy.
