Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

The only way I could completely block the driver is by riding on the wrong side of the road, I am pretty sure no cycle training would be telling me to do that!

Guessing you are in London? I am in the New Forest but if you are ever down that way I will gladly show you the main problem areas. Can also give you a bit of off road training too :-)

The view from Google earth/other maps doesn't show the blind hill (just looks straight) and the two blind corners don't look it from the air, but they are both blind (I also drive so know this)

will let you know when in the area

if by riding on the wrong side of the road going round a bend gives you better visability so you can see oncoming vehicles as well as prevent dangerous overtaking why not?. If something is coming towards you have room left to move back into your lane...you may get hooted since drivers may struggle to understand your position in the road but one day they'll get it
