Raikkonen, who started his F1 career in 2001 with Sauber, believes the cars haven’t changed much over the years in terms of the driving sensation, while the Finn contends that the physical challenge is perhaps a factor of the individual cars or tracks.
“I don’t think it felt any different in the earlier days,” said the 39-year-old Alfa charger.
“Some races are harder than others. In those days we did a lot of testing and then you just get used to more.
“But if you are driving it’s always going to be hard to go fast and be on the limit.
“Sometimes it feels more easy. I remember sometimes when we had a very good car and everything is absolutely perfect, it feels like nothing.
“You drive easily and the laptime is great, everything is great, and it feels a bit too easy. But other times it’s a painful experience when you have to fight.”
