struggle to. I've used lots of RMs and lots of bendy busses, and the two
aren't even comparable when it comes to speedy driving. Bendy busses
out-accelerate RMs, which counts for everything in London traffic.
Force = mass x acceleration. Ye canna break the laws of Physics. I already
knew there's lots more mass in a bendy - now you're saying there's more
acceleration too?

I know all about Mr. Newton's laws, thanks. If we're talking about
efficiency, you can't just look at f=ma and expect to know exactly what's
going on. That's ridiculous. Look at how efficient the engines are. If
the engine generates force more efficiently than the RMs, your whole
assertion is thrown into question.

I'd be surprised if they get as much as 5mpg. In Central London buses
almost never travel at constant speed.

More guesswork.
