Indycar racing does have a few interesting races on road courses, e.g. Sonoma, RoadAmerica, Circuit of the Americas, and especially Laguna Seca.
That said, indycar racing can resemble bicycle racing when it's sometimes just a peloton with the winner timing when to dash for the finish after playing following the leader for most of the race. Indycar roundyrounds (with the exception of the 500) remind me more of stock car racing.
Indy hasn’t raced at Sonoma for a number of years.
Verstappen won by 27 seconds today. That never happens in Indy car.
Any given F1 race, except maybe Monaco and Singapore, the bottom ten cars are routinely being lapped by the top four or five cars- that does not happen in Indy car.
