Lewis Hamilton has reportedly agreed to contribute $30,000 to the formula one drivers' union, despite still not wanting to become a GPDA member.

The development comes after Grand Prix Drivers' Association stalwart Jarno Trulli slammed the few active racers - including Adrian Sutil and the two Ferrari drivers - who are refusing to get behind the safety-oriented body.

The Italian revealed that the fees for GPDA membership are $1000 upfront and 200 dollars per point scored.

"If the top guys are uninterested, there's a lack of money for the GPDA to survive and it's always the unlucky ones, the ones who get paid less, who have to sustain the costs," Trulli was quoted as saying.

"What I don't understand is if you might not want to be part of the GPDA then you can do what you want but at least pay the money since you go on the track too," he added.

The Daily Record reports that Hamilton, the 23-year-old McLaren driver who has scored 20 points so far this season, did indeed agree to "dip into his salary and fork out his share".
