People have been complaining about the lack of passing in F-1 since, well, probably at least since the late 60s, maybe longer. After literally decades of trying, the sport's governing body, the FIA, has finally stumbled into a set of regulations that have improved the situation. Result? People start biatching about how easy passing has become.
The main difficulty, really with any road course racing, is getting around someone who's just a little slower than you are. Alonso lost his championship last year precisely because of this problem. KERS and DRS seem to have neatly solved this problem, preventing slower, more desperate drivers from holding up an entire train of faster cars behind them. Quit yer griping and enjoy the damned show.
