F1 in America

Why isn't the USA into F1?
Drive to Survive has sucked me in, and I can't figure out how America isn't onboard with the sport.

Well for start race time on US too early, then there is the INDY series. I start following a little bit more of Indy races since F1 drivers jump to the series. Romain is doing a suberb work. Also Alonso with Andretti, that 2017 500 Ml Indianapolis, was awesome!
The 500 i never miss it!
