$80 Billion was spent between 2014 and 2017 on R&D of autonomous vehicles [1]. That's 12 Billion / year (& numbers from a while back - I'm sure investment has kept going). The US government spends ~18 Billion on the entire DOE, the majority of which appears to be keeping facilities running / maintenance (even though it classifies all of that as R&D) [2]. Fusion saw about ~4.7 Billion in funding in 2022 [3].
Orders of magnitude matter and fission / fusion R&D has been criminally underfunded for decades.
