Unfortunately I don't have the time at the right times of day to race online. I did do a couple of seasons of iRacing a few years back and loved the competition with real opponents, but ever since my daughter came along (now 3 years old), together with work commitments I've don't have time unfortunately. Tried a few Sim Racing System races also but again can't commit to it on any kind of regular basis.
Really impressed with the AI though since it got the big update recently. I'm going to start to do more races in different cars/categories. Planning on doing a British F4 championship - all the tracks are available - just awaiting the RSS F4 car to be released on Saturday
Not sure I'd like the helmet mod. I like to have the view set up really far forward so that my actual steering wheel is where the car's steering wheel is, so it would look weird to have a visor tint on the screen. I have an ultrawide 34" monitor and move that out to just behind the wheel base, so it's pretty immersive - the next step would be VR, but that will have to wait some time due to funding issues!
