I think the Villenueve is feeling the pressure of being part of a three driver team at the worlds greatest motor race. He will also be in for a shock if he ignores flags (which he has a record for). It won't be a stop go penalty like in F1, it will be a 4 or 5 minute penalty and will affect the two other drivers in his car. He is used to the lone wolf style of racing in sprint races. Endurance is a team effort between the drivers and the pit crew. Also driving at 200 mph in the pitch dark is also something that will be alien to him. The first time he will drive the circuit at night will be in Wednesdays second qualifying.
