Coulthard wants to ban refueling
"In the days when you carried your entire race fuel load on board the car, there was a much bigger role for the driver in managing the tires and brakes," Coulthard wrote in his column for ITV.
"You could decide to run non-stop if you could make the tires go the distance, while someone else might pit twice," he added. "And because the car's weight changed so much more in the course of the race, there were more fluctuations in performance and handling characteristics, which in turn created more overtaking opportunities."
"These days, in dry conditions, you very rarely see anyone win from further back than the second row of the grid, because race pace largely mirrors qualifying pace – which is not surprising when the conditions are so similar," Coulthard went on. “So if we need to spice up the racing, in my view one of the best ways of doing that would be to ban refueling."
