I disagree. Braking skill is an important part of driving skill. Same for throttle modulation skill vs traction control. Good drivers will still rise to the top, but those aids are overly equalizing drivers and not giving drivers with better brake and throttle skills opportunity to use those skills to their advantage*TLDR but what is the problem with on-board electronics (ABS, TC) in racing? As long as everyone in a race has it, it makes the skill of the driver the most important factor again. I'd agree if half the field in a race had assists and the other half didn't - you'd then be potentially be winning because of the tech. For a series like GT3, because the assists are there for everyone, they effectively cancel out any advantage and it's then back to the engine, car design and driving skill. It will never be easy to drive at the top level as long as the driver has input into the system.
Here is what Shane Van Gisbergen had to about his time in GT3 cars compared to his normal Supercars:
“These cars are easy to drive on the limit. You just drive on the (electronic driver) aids,” Van Gisbergen told Supercars.com.
“You just press the brake as hard as you can and it just stops. It’s a lot less skill and technique than a Supercar."
*That is perhaps a bit simplistic as good GT3 drivers are often dialing down the traction control (depending on the turn, tire life, strategic need, etc) trying to get better acceleration at the risk of some wheelspin
