Jules Bianchi and Tech 1 racing have called for rule changes to prevent drivers from winning championships by colliding with their rivals.
Ferrari junior Bianchi lost the Formula Renault 3.5 championship to Robin Frijns at Barcelona last weekend, following a clash between the two when Frijns tried to re-pass the Frenchman for fourth place.
Race officials judged that Frijns was at fault for the crash and handed him a time penalty but he held on to his title because Bianchi had retired from the race as a result of the incident.
"It's too easy now to win a championship like this," Bianchi told AUTOSPORT. "He deserved more than a penalty.
"If nothing happens then people will think it's fine - if you are first going into the last race, just do something like Robin did and that's it.
"We are not F1, but we are still a big series, and a lot of young drivers are watching us - guys in Formula Renault 2.0 or karting.
"And this is the example we are setting for them? I don't think this is the right way to do it."
Bianchi's Tech 1 Racing team boss Simon Abadie added: "Sport did not come out on top this weekend.
"Concerning the way in which the outcome of the battle for the title was decided, Robin Frijns did not exactly cover himself in glory.
"For this type of manoeuvre in Formula 1 in 1997 Michael Schumacher had all his points cancelled.
"I think the World Series by Renault authorities should be much more severe about behaviour of this type by young drivers."
