Even where there is a "bus service" of sorts, buses don't even connect well between routes.
My son does a 7 mile journey between his University campus and his team's football stadium. Obviously a Uni is a main "hub" for buses, and the image looks good as there's literally always a bus at the main square, often 2 or 3, with departures literally every 5 minutes or so. But there are no direct buses to the football stadium and few direct buses to the city centre (first change point) so even the first stage takes ages as the buses go all round the houses to get to the city centre bus station. OK, a change isn't the end of the World. But it's not just one change, it's 3 changes at various places, so a total of 4 buses to go just 7 miles between two pretty large/important places, both having lots of people wanting a bus from each point (Although granted, not too many wanting that exact journey but lots wanting to go elsewhere from each end). But even from the city centre main bus station near the Uni, it's still not a direct bus route and still needs at least 2 changes en route.
I've just checked on Google and total journey time by bus is whopping 94 minutes (remember this is only 7 miles) and that isn't even door to door as there's still about half a mile of walking. Direct door to door bus would be over 2 hours.
It's only 2 hours 15 minutes to walk the whole route!
In fact, yesterday's game, he did walk most of the route as the buses were chaotic due to some road works, services randomly cancelled, etc. He got off half way between Uni and city centre to walk to try and get the bus from city centre towards the Stadium, but he missed it by a couple of minutes and it was only an hourly service, so he took a different bus in a slightly different route, and got off half way on that and then walked a mile or so to get to another route to get a bus for a mile or so, then got off and walked the rest of the way.
When he rang last night, he says he's taking his car to Uni after Easter - he didn't take it as he thought the buses would be OK with it being a Uni and the image of buses everywhere, but yesterday was the last straw.
