No it's not. The lead driver defends by staying on the racing line which is always the fastest entry to a corner. The attacking driver tucks in behind him gaining a draft and if he judges it correctly will gain enough tow to slipstream past before the corner, though he's forced to go off line to achieve the pass. The overtaken driver of course has the opportunity to do the same and regain the place on the next lap. There are certain circuits that lend themselves to drafting, Monza is one though there are others also. If you watch racing from the 60's right through to the 80's drafting was the norm and it was totally unacceptable and considered dangerous for the driver that was being attacked to swerve to prevent an overtaking move. Formula One appears to be the only top level form of motorsport that allows the one move rule, in other words blocking. There's plenty of overtaking in open wheel racing in the US, on the ovals and road circuits, but if a driver tries even a half block he will be black flagged. It's not tolerated for safety reasons and in the interests of good fair racing.
