What alternative would you suggest?
The £2 bus fare is flexible and cheap for people. Any period ticket would cost a lot more upfront and therefore require people to commit making it less available as and when. Even if you use the £2 bus fare 5 days a week for a return journey you're only just getting to that 49eur, and as you say any period ticket would end up being far more in the UK. I'd like to see something that includes trains which is presumably what you're alluding to but I just don't see it happening without losing any of the value and flexibility the current £2 bus fare has
Getting people to commit is my whole point - persuade people to form habits that don't involve their cars, and hopefully those habits will stick. Once you already have the ticket, the marginal cost of a bus journey is zero. I bet there are people, for example, who under the current scheme use the bus to work to save on parking costs, but at the weekend they're straight back in their cars. If the bus is effectively free, they could be converted into weekend bus passengers as well. The buses would be running anyway, so there is no loss of revenue. Similarly with park and ride - it's an easier sell if the bus journey is free, and that should hopefully persuade more visitors to forgo driving into city centres.
The £2 fares are a nuisance on busy routes. Instead of 10 people just getting on and scanning their period ticket, you have 10 people getting on, asking the driver for a ticket and then more often than not going through a whole card transaction, sometimes having to repeat if it fails the first time. It's widely accepted that to run an efficient bus service you need some way of taking the workload of issuing tickets away the driver, whether that's ticket machines or some sort of online system, but the current scheme totally undermines that. It also penalises passengers for having to change.
As much as I would like it, I don't think train validity is realistic. But I think something like a monthly subscription ticket for all bus and light rail in England, at an emminently affordable price, should be achievable.
Not sure I agree with that it's quite a simple system really.
Mind I do think the cap needs amending so it's something more like 50p + 10p a mile, with a minimum fare of £2.00. I'm not sure someone travelling 65 mile from somewhere like Newcastle to Berwick can really complain about a £7 bus fare. £2 is outragerously too low though for that journey.
I think it's pretty fair that someone travelling further than 15 mile should be expecting to pay more than £2.
I'm not sure this in and of itself is a good justification. The fact that something is simple doesn't necessarily make it a good idea, and indeed the current system has quite a few shortcomings which I've discussed above. Plus of course changing a £2
maximum fare to a £2
minimum fare is unlikely to go down well with the public (especially bearing in mind there are still a few journeys where you can pay less than £2!), and your suggestion of mileage-based pricing does rather add complexity
