Gridlife has definitely grabbed my attention moreso than the other racing series recently. I think the explosion of interest is also relating to accessibility and inclusion (price and range of vehicles that can be entered). It seems that whenever a new racing series or group comes out (ex. SCCA > NASA > Gridlife), they try to make it easier and easier to join (maybe sometimes too easy, carry a fire extinguisher!). From a viewer perspective as well, I like seeing the vast array of different types of vehicles on the same field. I started in autocross and figuring out my class and PAX based on SCCA rulebooks took me longer than I'd care to admit!
