Juan Pablo Montoya believes DRS has devalued the art of overtaking in Formula 1 since it was introduced to the sport.
The Drag Reduction System, which boosts top speed while lessening aerodynamic drag, was brought into racing at the beginning of 2011 and has led to plenty of action during Grands Prix.
However, Montoya suggests that while DRS has made the sport more of a spectacle, it has taken away from the art of overtaking.
The ex-Williams driver told The Racer's Edge: "Now it's like giving Picasso Photoshop.
"You had to think and you had to risk a lot. You don't have to fight for the positions now.
"You come into the straight and if you are close enough you have DRS and you've cleared the guy by the next corner."
Montoya left Formula 1 in 2006 to race in America's NASCAR series before switching to IndyCar.
