They are not dumb. At least the 1S Lipo thing is not dumb. What it has done is allow the oval and road course racers to get the benfits of Lipo (and move away from NiMH technology) without either: a) having cars to fast to be controllable, or b) needing to run motors that are not readily available.
There isn't a lot of choice for pack voltages when using LiPos. Using the 2S lipos common in touring cars and 1/10th scale off-road cars makes carpet cars too fast for most people to drive even with the slowest motor available, the Novak 21.5. So by using 1S LiPos, they now have a selection of speeds that can accomodate entry level racers (17.5/1S) all the way to experienced drivers that want really fast cars (7.5/1S).
At my track the current record for 1S/13.5 pan cars is 90 laps in 5 minutes. or an average of 3.3 sec/lap. They are not slow by any means. They are averaging 23 MPH around an oval in a space 35ft by 60ft. Unless you have driven on carpet, you have no idea how fast these things can go when traction is essentially unlimited and you don't have to lift for the corners.
Do you have a car that can make a U-turn in the width of the typical driveway at 20+MPH? And do it 180 times in 5 minutes? 1S Lipo isn't dumb just because you do not have a car where 1S is useful.
