I don't have to contemplate small business ventures, I have a small software company...

OK, technically I’m a small business owner too, I haven’t been an “employee†since 1997, but we are very small and mostly work for ourselves with the occasional sub-contractor. So I don’t really consider myself a business owner so much as being self employed.
But never mind our differences, take John up on his suggestions and offer. I get how frustrating the cars are to drive and I suspect that the longer you have driven a real car aggressively, racing or otherwise, the harder it is to master the sim. I was unable to complete even a slow lap at first and kept thinking it was the calibration of the gear, or crappy software, or
something. At slow speeds the cars certainly seem to act in ways that you couldn’t even provoke out of a real one. I still don’t get that, but at speed I think the car dynamics are probably as good as they get. But, I still suck big time. Despite having a very good wheel and pedal set I just don’t enjoy it much so I didn’t put in the time to get better. Then I was sure that the Rift would be THE difference, and it certainly does help the realism and increases the enjoyment, but I still don’t make the time. ¯\_(シ)_/¯ Something tells me retirement won’t change that.
But obviously there are a lot of guys who have mastered it and some very talented racers have made a rapid transition from sim to real. I suspect that it more exposes raw talent in people who might not otherwise have dicovered it, than creating talent from the average joe, but there is no doubt that it and other realistic sims are a valuable training tool.
Sorry to ramble on mostly the obvious but I think there are a lot of people who share your experience and would benefit from sticking with it a bit longer.
