this is why i said 80mph not 30mph. To inherent instability of 3 wheelers one also need to add inherent instability at speed of low-weight small vehicle with high height to width ratio (an issue arising from aerodynamics) what 3 wheelers are. The best one can get is a T-REX like (http://www.campagnamotors.com/ http://www.campagnamotors.com/). Now, if somebody managed to sell T-REX at $7K instead of $40K+ - that would be something :)
