Usually, most beginners are limited by cost and expectations. In reality, beginners who are taught how to adapt can start reasonably well with almost anything especially if they are young. If they are coached and able to relax and adapt their grip, they can do far better than some of the supporters of slow blades would think. It is possible for a learning driver to use a Lexus to learn to drive even if it isn't what you think they should be using.
The parallel to car driving doesn't really end there; there's an idea in the performance driving world that beginners should start with easy, slow cars and work up to more performant ones when they gain more skills.
This idea is mostly based on the fact that easy, slow cars are cheap and you can actually buy them as a younger person but it also has some merit in that the handling limits are generally less sudden due to being lower and using more compliant rubber and the power is lower so it's not as easy to use too much on the corner exit and doesn't require as much timing and finesse on braking due to speeds being lower. Sound familiar?
I mostly agree with this because it's economically more practical and generally safer, but there's a few real problems with it once you start getting into actual performance driving.
People who learn on slow cars without "advanced" things like sport ABS, sensitive enough tires or high enough engine power end up learning bad habits like not braking hard enough on the straight and deeply enough into the corners, not feeling the tires enough and over-using them as a consequence, mashing the throttle and not really paying attention to how much power they're using because there's no real punishment for it and so on.
Then when "the time comes" and they finally "move up" to a "real car" (generally this just means they are economically able to and has little to do with driving ability) they're completely unequipped to handle its new challenges and have essentially still beginner-level skills when using the new equipment and have to learn from scratch anyway.
Meanwhile the kids who grew up driving simulators and not very limited by what kind of car they're able to get the chance to drive will jump into a real racecar and bang out relatively competitive laptimes without any guidance, even if the real car is often a little bit more complicated and more difficult to manage.
I'm not really sure how you think anybody ever tries new equipment then? You think every amateur tries something for 1 week max and then makes a final decision? Playing matches and even tournaments are part of the testing process...
The real EJs will only try equipment for 1 hour max before making a final decision.
