I actually seriously started looking at buses again, moving offices shortly to one that's closer to the city centre (the only place the buses go to), and I'll spare the details, but it's still going to be quicker to walk the whole distance.
If one of those things of the actual fuel burn is around £1.60 to get to work and back, maintenance attribution costs take that up to around £2.50, and then annualised tax and insurance around £4. (There's no leasing or PCP costs, I own it.) So even taking all the costs everyone forgets into it, it's still actually cheaper to own, run, maintain, insure and fuel a car to drive to work than it is to take the bus, and it's quicker to walk than take the bus, and this isn't a cross city or weird journey, it's from a city's outskirts into the major employment centres.
Unless there is a major shakeup of routes to cater to commuters rather than retirees going into town, I honestly can't see a shift of commuters to buses any time soon in this city, and in a lot of other cities that I see.
If I had to pay to park at work, I'd just walk or cycle, because it's quicker and not reliant on a service that has issues.
Oh and a PS, I have to carry a *lot* of 'accoutrements' for my role, so cycling or walking most of the time isn't practicable anyway.
