Sorry to veer slightly off topic here but I wanted to comment here :)
Most members of the hardcore Mario Kart community (which is surprisingly large and dedicated) think that "snaking" (back and forth mini turbos) is what make time trialing so INTERESTING in Mario Kart Double Dash and Mario Kart DS. It does add nuance-- ordering of mini-turbos, the line through the course that allows the most mini-turbos, the speed of mini-turbos, the consistency of the mini-turbos. I think that much the same could be said about barrel rolls for time trialing in Wipeout Pure and Pulse.
My problem with snaking in Mario Kart isn't the technique per se, it's the terrible strain it puts on your hands to implement it. At one point I was somewhat highly ranked in Mario Kart DS (maybe 30th in the U.S. and 130th in the world, amongst perhaps 600-800 dedicated participants?) but retired to save my wrists. Barrel rolls, in contrast, just aren't that taxing on the hands-- at most we are talking about 5-10 per lap rather than dozens and dozens of mini-turbos in Mario Kart.
Personally, I think the main issue with barrel rolls are that they can't be consistently done in head-to-head races and multiplayer because of the framerate. For time trialing, however, they work well and DO add several layers of strategy and planning to the process.
Anyway-- I completely understand that some of you long-time wipers dislike the barrel roll, and I'm sure that coming Wipeout games will be good even if the mechanic is scrapped.
But I DO hope that, whatever takes the place of barrel rolls, adds a similar level of complexity and nuance to the racing mechanic. We do NOT want obvious perfect laps that can be achieved with a few days of practicing! (At least, not in my opinion :) )
