Why not ? does it not appeal, or has it just not been convenient ??
Time, expense, ability...
While I am not the worst rider on the planet, I am definitely not the best but I dont like to give anything but 100% effort in matters sporting. This leads me to believe that when riding a track I would do the same - the problem being that this is my only method of transport and any binning it will result in busses for the next decade because I am not exactly wadded with cash atm

It does appeal and when I get a car soon, I will no doubt attend a few, although knowing no-one with a bike doesnt exactly help

do you think you'd feel out of place because of your riding style or your bike ?
Not at all, I think the best place for this bike is on the track, its pretty much purely about racing rather than any real life practicality. The CBR 600 RR is gagging for some track abuse, but I think I'll fit a steering damper first, stick some summer rubber on and then get the suspension set up for my fat arse

It often confuses me why people have no desire to get out in what's arguabely a far safer environment than any road scenario.
Why does it confuse you? Not everyone would like lapping the same bit of featureless tarmac all the time. I am sure that some people, myself included would prefer the open countryside at a slightly less breakneck speed with all the scenery and road variations this entails. Dont get me wrong, I'd love a trackday now and again as well, but I dont think that I would ever prefer it to the roads in summer
do you think it would bore you going round and round the same route time after time, lap after lap??
No, but it might do for some. I would enjoy it as a change, but not as the primary use of my biking time
