max:50 to 60 mph
There is no saying that buses aren't allowed on fast lane or slow lanes. It largely depends on the speed those buses are actually travelling in. For different countries, there are different road rules, travel on the slow lanes if buses are travelling on a relatively slow speed to avoid road hogging, while for fast moving buses, they can travel on the faster lanes if they can maintain speed to suit the road condition.
60 mph
There is a fast train service from Victoria Station.
That depends on how fast one is traveling.
It is really very fast, compared to street transport like buses, it is pretty cheap, and you can do as many interchanges you want with one ticket (until it expires), unlike with buses where you need a new ticket every time you get a new bus. It also has an awesome history.
Most buses got a governor. All I know is that our buses go 234 mph.
London is not sinking.
The Fast And The Furious London Pursuit was a hoax. It was actually called Fast & Furious (Fast & Furious 4), which came out in 2009. The series did go to London in Fast & Furious 6 in 2013.
