For some lines that go above ground (Northern, Jubilee, Central), the driver sometimes had to put it into manual mode to compensate for the worse breaking when it's raining outside.
Well in the UK the subjects you select is very closely tied to which University you can go to. Some universities require maths and will not accept people who haven't done it (sometimes even more advanced maths is required).
Some universities don't require maths and so will teach it to everyone who's applied. Some don't require it but force you to take a year of it if you haven't done it. and others require it and reject you if you haven't done it.
In the UK the details needed to transfer money into an account are on most bank cards (Account Number and Sort Code), so that's enough identifying info.
That would also mean someone can send you money if your card is blocked or cancelled. Account number and sort code don't change when you get a new card.
Also, "Faster Payments" is the name of the normal system to transfer money between accounts in the UK. It doesn't cost the sender anything other than the money they send. It's called "faster" because the old system was a lot slower (because it was based on paper I think?).
This font reminds me a lot of "Rail Alphabet" which is a font designed by British Rail in the 60s which was used to railway signs and also in hospitals. Newer fonts are starting to replace it, but there is still a lot of it around if you know where to look.
This concept is not new at all, From what I understand the tunnel sizes proposed are barely bigger than the London Underground "tube" tunnels. (Glasgow's subway has even smaller tunnels too). Now, don't get me wrong, it worked quite well for London, but it's not exactly innovative.
