Why so negative? Most bus depots are practically empty by 0800 (on weekdays): who is using those buses? Concessionary passes aren't valid at that time and schoolkids certainly aren't filling all those buses. Your location is apparently Reading: perhaps you should spend some time observing the operations of your local bus company and then try suggesting that people don't use buses to travel to/from work.
Obviously we don't have a command economy that could dictate how people travel though I get the impression you would be happy if that was indeed the case. Nevertheless buses are being actively chosen by many. Indeed more people travel by bus each day than by train. I don't believe all those people have no choice.
The buses might all be out by 8am, but it is a very fair point that bus services in many parts of the country are not designed to cater to commuters. How many major employment sites have no or very poor bus service? You look at timetables, how many routes have reduced frequencies at peak times because the operators won't use extra vehicles to accommodate longer journey times, or take vehicles off public services for school contracts?
The obvious issue is that without subsidies it is not profitable to have lots of buses sitting around only doing a handful of peak journeys a day. The UK has generally chosen not to subsidise buses for people travelling to work.
