Williams driver Felipe Massa said this week that overtaking won't always prove as difficult as it was in Melbourne.
But he agreed that the Australian Grand Prix had been a disappointment in terms of wheel-to-wheel action to kick off the 2017 seasoon.
"It's a lot harder to get past now," he acknowledged in an interview with Brazilian broadcaster Sportv this week. "But that was clear as soon as they changed the rules.
"But it depends on the track. Australia is always a difficult circuit to pass on, so it will not always be like that."
"It was always like this, until they invented the DRS," Massa added.
"In the old days, the position you started was more or less where you finished if you didn't make a mistake or have a problem.
"So it will not be the same as it was in the past, because of DRS. But if we didn't have DRS, nobody would pass anyone."
Massa added that Albert Park Circuit was not the best example on which to base predictions of the rest of the season.
"There will be harder circuits," he explained. "Australia is not very difficult on the physical side.
"But in Malaysia it will be very hot, for example," he continued. "There are circuits on which we will feel it on the physical side, and if you get tired, the chance to make a mistake is greater.
"I finished the race in Australia well, but without doubt it's harder than before.
"But if you look at the drivers, everyone is training. Most of the drivers are very professional. Maybe Hamilton a little less!" he quipped.
