We have a lot of old codgers here in Bude and the standard of driving is execrable (I won't dwell on this outburst of whataboutery...) I have an electric Brompton which, if I wanted to, I could hammer along on at at least 20mph, which I don't. The electric assist cuts out at 15mph, after which is goes from being a breeze into being a right heavy bugger. My brommie is for tootling only.

And I've just typed a sentence there, perfectly grammatical, that has "at" twice in a row! In tandem, eh? (see what I did there?)
