1 second is all you need in this F1.
1 second is what you need to be able to use DRS and get an easier life with overtaking.
I agree, one second is a lot of time in Formula 1. This year and in the last few years, we have seen that RedBull has and had the most perfect pit stops in the last few years, and Ferrari has felt the bigger slip-ups, with Mercedes in the middle. A quick and well-timed pit stop can, for example, mean being in front of the competition at an undercut or falling behind the driver behind if there are problems.
RedBull had the fastest pit stop in F1 history with 1.82 seconds, 1.82 seconds you have to imagine, unfortunately the FIA introduced a new rule and stopped RedBull's extremely fast pit stops.
