Trail braking can be used in every type of car, we use that technique in mid-engined formula cars to initiate rotation, which you control with maintenance throttle mid-corner and transition to slight understeer (with chassis slip angle however) on corner exit, for fastest lap times and repeatable control. Of course I understand there is a different type of driver interested in a forward trike car, and those looking for a car which turns in crisply and can rotate well under high G cornering, but I wouldn't ever consider a forward trike because I know I'd flip it over because of that high CG, and instability on corner entry. Even if you don't drive hard, if you need to brake and avoid an obstacle, it would take a lot of conscious effort to brake in a straight line toward the obstacle, and then gas it hard for rearward weigh transfer so you don't barrel roll into the obstacle trying to go around it. Braking with a single front wheel will suffer too, so you'd want to instinctively go around it if it's too late to stop completely, at which time you'd have to worry about flipping. On my emotard I gotta sit far back on the seat under hard braking or it'll do an endo, and it brakes twice as hard with both tires making contact with the road. Honda stopped selling their 80cc trail trikes because of all of the lawsuits, my buddy that had one flipped it over more times than I could keep track of, that bike worried his mom so much!
You must be a skilled driver dicing it up with BMW's in a Robin, Mr. Bean clowned on his nemesis in a Reliant in a clapped out Mini! lol
