Very true, but a fundamental technological inability to overtake will certainly make for a poor race or sometimes no race at all, and that can't be a good thing. People talk about DRS producing "artificial over-taking" but I think that is nonsense. DRS is there to provide a means of allowing racing whilst maintaining a competition between highly developed aerodynamically designed racing cars.
I want to see the most highly developed racecars in the world and I also want to be able to see them race. DRS, in my opinion, is a very elegant solution to be able to provide just that - not just for the spectators, but also for the teams and drivers, who are also mostly in favour of it.
The only drivers that really seem to moan about it are the Red Bull drivers but that is because straight-line speed is often the achilles heel of the machinery they have.
Now what is artificial is the tyre design which, as Pirelli will attest to, is purposefully designed for sub-optimal performance. The same is not true of DRS, although the method of application is.
