all your conclusions from that. The engines on the new busses, and all the
bits connecting them to the wheels, are brand new designs (compared to the
RMs). "Wasted time and fuel in traffic"? Bendy busses can overtake traffic
RMs would 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'd be surprised if they get as much as 5mpg. In Central London buses
almost never travel at constant speed.
