Simulating INDYCAR's Unknown: Inside Drivers' Prep For New Street Courses

INDYCAR drivers are leaning heavily on the Driver In The Loop simulator to learn brand-new temporary street circuits — great for layout and rhythm, but often wrong on grip and bumps, so expect on-track surprises.
Markham’s entire 2.19‑mile circuit was repaved (rare for INDYCAR street races), meaning more consistent grip, fewer bumps, stiffer setups and a bolder layout with elevation — likely makes for exciting, unpredictable racing.
Two back‑to‑back debut street races (Markham then Washington, D.C.) are unusual and mark a new chapter in Canadian INDYCAR history after moving from Toronto’s Exhibition Place — perfect chatter for race fans.
