When it comes to the racing, there are a lot of things one could say Formula One needs— without everyone else breaking down or vanishing into thin air, less predictability, , and, of course, . The good news is, the folks at F1 think that last one may improve this year.

They’re not talking small improvements, either. reports that F1 thinks overtaking numbers could increase by 50 percent in some races, based on simulations its technical folks have run on the new aerodynamics regulations.

The lack of overtaking in F1 has been a big deal in recent years, especially the dismal 2017 season, when the per race was half of what it was the year before. But F1 introduced regulations for for this year in hopes of changing that, in addition to its existing to help overtaking, and simulations show that it may just work.

Motorsport.com cited the FIA’s Auto magazine in quoting the FIA’s head of single-seater technical matters , Nikolas Tombazis, about the simulations. Here’s what he said, from the story:

“Some simulations were showing a +10% increase of overtaking, assuming a similar evolution of a race, of course.

“In other races the same simulations expect a more sizeable increase, possibly to the tune of +50%.

“That’s the feedback we’ve had so far, but it will really only become clear as we progress through the season.

“We weren’t expecting miracles in round one at Australia, but generally we are expecting a step in the right direction as far as aerodynamics are concerned.”

There don’t appear to be comprehensive overtaking numbers for the 2018 F1 season online, but the 2017 season was when things really didn’t look great. Pirelli that there had been 435 overtakes that year, or an average of 21.8 overtakes per race.

Combined with data from 2001 through 2016, the numbers from 2017 were the worst they’d been since the . But two years later, aero regulations have undergone a slight overhaul to try to trend those numbers back upward.

The 2019 aero regulations in F1 simpler front and rear wings as well as a simpler design on the front brake ducts, meant to make the racing less spread out. The series is two races into a 21-race season—the opening Australian Grand Prix, which isn’t an easy track to overtake on regardless of aerodynamics, and the , which was fun to watch for and . Given that we haven’t seen much racing yet, it’s hard to gauge how much of an impact the new rules have had.

But there are 19 races to go this year, meaning we have a lot of time to see—and hopefully enjoy—just how much of an impact these rules may have.
