Paul Dutoit - any information?

I remember coming across this memorial plaque along Golden Hill Road a few years back and was wondering if anyone could shed any light on what it was doing here. My only knowledge of Paul Dutoit is that he was a Belgian racing driver in the early part of last century, but is this the same chap?

The plaque is fixed half way up the side of a cutting along Golden Hill Road - well out of reach of passersby - and I am assuming that this road once formed part of some sort of car race.

I'm grateful to any HK motorsports enthusiasts who can point me in the direction of more information.
