twitchier
adj.— «The cars will be further slowed by the raising of the front wings by 50mm which will reduce downforce. In Formula 1 parlance this should make cars “twitchier” to drive and more spectacular to watch with less grip.» —“New regulations intend to revive F1’s competitive edge” by Alastair Moffitt The Scotsman (Glasgow, Scotland) Mar. 5, 2005.
