The problem is that most of the stuff that makes drag racing so fun (and difficult) in real life is missing from LFS. In-game, the conditions are always the same. Once you find a good setup, there's no reason to ever change it. Track temps, rubber groove, a working clutch, blown engines, stalled cars, clutch/transmission/rearend damage, etc. Not to mention the longitudinal grip issue (which I think will be fixed in Patch Y, if Scawen's comments are any indication). These things are what makes getting a good quarter mile run so challenging, but they are not simulated in LFS.
I think drag racing in LFS is going to remain very niche until we get some sort of changing track conditions that necessitate different tire choice, picking a good line, heating the tires properly, etc. But, every little bit helps. Today is false starts. Maybe tomorrow will be proper staging and a better clutch model with the ability to bog the car and stall.
