On the flip side we have messes like East Midlands Parkway - a massive station with huge overheads, which is barely used, not helped by the fact the airport buses stopped.
On the flip side it was an extremely handy railhead during the Nottingham blockade, and the former power station site is earmarked for a significant amount of residential and commercial development.
In the future we may look back upon it as an extremely unusual modern example of building a station before it's needed, rather than years after!
How many places have gained ‘new’ bypasses in the last few years? Here in the Peak District it was some while since the last one as far as I’m aware (Chapel-en-Frith). This is despite us having one of the earliest (Taddington). Mottram is finally seeing some improvements after decades of stalling.
Don’t confuse junction safety improvements (often to benefit pedestrian or cycle movement or to access new housing or even rail-served freight interchanges) with ‘traditional’ small town or village bypasses.
Broughton and Penwortham in the Preston area - both also seeing some of the bypassed road space reallocated for active travel - rather than simply inducing demand and resulting in the same issues 25 years down the line!
Preston has also finally seen the construction of a part of its Western bypass which was originally identified as being needed by the 1980s, although a significant justification was to support new housebuilding in the expanding city.
This is going to become a massive issue long term - once people can access relatively cheap autonomous taxis, the incentives to use buses disappear. Why spend £3 on a bus ticket when you can get an autonomous taxi that takes you from door to door for £5. There will likely need to be some sort of duty on them to ensure that crippling congestion isn't caused by their rollout, especially in major cities.
And probably more importantly dedicated space that's not shared with taxis - £3 and takes 24-26 minutes or £5 and takes 15 - 90 minutes is a whole different kettle of fish. Undoubtedly there will also be a shortage of vehicles at peak times, or significantly higher fares to cover the costs of vehicles sitting idle most of the time.
