I beg to differ.

The speed with which some bendies are driven (my experience is mainly
on Red Arrow route 521), especially around corners and on uneven ground
(and on inclines such as the Kingsway subway) is truly shocking. And
the habitual corner-cutting at places like Waterloo Road into Sandell
Street is appalling. I have bruises on my arms from being flung around
at that location, and my head has come within milimetres of hitting the
ceiling on several occasions. This is especially so when sitting in
the extended articulated part of the bus, which has the effect of being
an exaggerated see-saw whenever the bus goes over a bump or change in
latitude.

I agree however that the acceleration / deceleration is smoother than
on some other buses.
