That will be fine on the Victoria Line because it's devoid of tight curves,
but benditrains on curvier lines sound lethal. I know it works on the
Croydon trams, but they are not as packed as a tube train.

You've obviously not been on line 1 in Paris recently, where fully
articulated stock is used on the line with (ISTR) the sharpest bends
on the network (around Bastille).
