Next Tuesday a gathering of Formula 1 stakeholders in London will, in theory, be a major stepping stone towards determining its future direction - a process that cannot start soon enough, if team bosses are to be believed.
The clock is ticking relentlessly towards 2021. Melbourne last weekend marked exactly 24 months until the first grand prix that's due to take place under new sporting and technical regulations and with a completely new financial framework.
For the teams it's substantially less than that to the cut-off point for signing off on key elements of the designs of their 2021 cars. And while F1 folk are noted for their ability to move quickly and think on their feet, the changes to the championship are so big and so wide-ranging that time will disappear very quickly.
