Also, I've not had direct experience of it myself (too poor - only have old bangers!), but these new cars with keyless entry and ignition, which make them very easy to steal. A remote fob was a very handy innovation, but what's the point of this? How does it save time or effort at all?
Also, contactless card payments. How onerous is it to stick your card in the slot and quickly jab at 5 buttons?
It hasn't even been built yet, but HS2. If you occasionally travel between London and Manchester, you can shave half an hour off the journey time - big deal. it would only make a big difference if you commute there regularly - and if you do that, surely you'd save much more time by moving jobs or living nearer to where you actually work?
It's not even like it will save most people much time anyway, unless you live in the middle of one big city and are travelling to the middle of another big city, you have the hassle of getting to one of a very few stations.
Instead of making already-well-served major routes a bit quicker, why not start with north Wales, northern Scotland and SW England, huge swathes of which don't already have very good direct links at all.
