I took my Locost to ice track couple a weeks ago (here in Finland!).
Short and shaky video:

Track was quite bumpy. Took only two laps to shake the six steering wheel screws completely loose.
One of the rear trailing arm bolts went missing too...
Tyres were old 15" studded rally tyres. I have only about one turn lock to lock and steering was very
heavy (you have to work against gyroscopic forces with these large and heavy tyres).

That looks like good fun

do you think he has any teeth left?

By the way I had about 30 psi on the tyres. It is rediculously high pressure but that's what people with experience recommended for these long studs. Probably works well with soft springs.

The rear view mirror made me laugh out loud!

Looks like loads of fun!
