Nelson told Sky news that when he signed the contract with the clause to achieve at least half as many points as Alonso, he thought that he would be getting equal treatment. It is only his second season in F1, he is in competition with a superb driver and former world champion and in most of the races he had a lesser care (in fact the car from the previous race). Talk about having to compete with hands tied! You are right that they had the same car in Hungary but Nelson was on a different strategy, carrying 30 litres more fuel (thats another fifteen laps). The drivers that were light on fuel performed badly getting caught in the field behind slower cars after their first pit stop. We don't know if it would have been the same fate for Alonso because he didn't survive his 1st pit stop. Maybe Nelson doesn't have what it takes, I don't know but his treatment certainly smells and I for one don't think he's been dealt a fair hand.

After the running on Friday Renault have an idea where their drivers are regarding pace. Obviously Alonso had a lot more pace and could go for the aggressive strategy where as Nelson was struggling and had to go heavy and hope for a pace car incident. Nelson has struggled a lot with bad practice pace so he had to go, look at Felipe Massa he was in the same situation a few years ago when he was only the Ferrari test driver for a year and made a better come back a year later. Just because his dad was great it puts a bit more pressure on.
