They are, the car is pushing "forward and to the outside" of turns. For some chuckles, here's Top Gear demonstrating the fact (over and over) https://www.youtube.com/watch?v=QQh56geU0X8
As a sibling comment mentions, the two-front, one-back configuration is out there in sport-leisure type vehicles. I think it appeals to people who want motorcycle-ish sportiness but maybe are turned off by the appearance of complete exposure or the possibility of dropping the bike.
Modern three-wheelers I'm aware of, on roughly the "car-ish <----> bike-ish" spectrum are the Campagna T-REX, the Polaris Slingshot, Can-Am Spyder, Piaggio MP3, and the Yamaha Niken. The first two are pretty "sporty car" vehicles, the latter two "complicated motorbikes", and the Spyder maybe a 40-60 mix, IMO.
