Buck,
Go to the iracing website, it gives you the minimum specs you need to run the sim.

Bouncing off other cars will be severely penalized with incident points, which will lower your safety rating, heavy car to car contact is 4 points, a slight door rub is 1 point, if it is very minor contact sometimes you will not get any points,even if you are the innocent party, you will get points.
You can be reported to the chief steward, who can serve you penalties, if you are deemed to be driving in a reckless manner.

This is not a game, it is a simulation (sim), it has a sanctioning body, and all the same rules and regulations of real racing series. The majority of the members, race in real life, either oval, road, karting, AX, DE, several Nascar drivers are members, a couple of IRL, as well as some other road race professionals.
I was taking to a guy today, who raced Dale Jr last night in a truck race.

There are no driving aids, traction control, ABS, just a good setup and a good driver, some of these guys are extremely fast and are on a different level than most, these guys take it very seriously, and you will be called out if you are a perpetual wrecker, or poor driver.
