RESPECT! - I reckon I couldn't have done it at a quarter of that speed!
It is nice to ride/drive with most of the unpredictable hazards not present.
I've hammered a V8 Comodore around a private race track and a skid-pan. I have also spent quite a few days (back in the early 1980's) hammering my Yammy XS1.1 around Adelaide International Raceway - aah! - those were the days. For most of the 80's I drove V8 Ford F100's around Victoria at emergency speeds. I once drove from Royal Kids hospital in Melbourne to Bendigo Base Hospital in a Ford V8 wagon in 58 minutes door-to-door - around 150 km's. Aah!, they really were the days!
I have survived my youth and most of my adult-hood. Sometimes only with a good measure of luck.
