Formula One has agreed to implement a new rule from next year which will see standing starts after every safety car period.
The idea has been met with a mixed response and is still pending the approval of the World Motor Sport Council.
"Apparently this is for entertainment reasons," said Toro Rosso driver Carlos Sainz.
He said his first reaction is that a mid-race grid re-starts "seem artificial", and may also be a backwards safety step in the event of wet races.
However, Haas team boss Gunther Steiner backed the idea.
"We all like starts," he said. "There is a certain amount of risk, but when there is a risk, someone can win and someone can lose. So I think it's worth it and a plus for all of us."
