I still don't see how that steering arrangement can be safe. If you are
driving at say 30 mph in traffic and you have to stop suddenly, you will be
applying brakes to your rear wheels. If you need to steer at that point you
will apply different amounts of brake pressure to your right and left
wheels.
This works very well as long as you have enough traction on both wheels.
What if one of the wheels is driving on wet pavement or sandy pavement as is
often found on the right side of the road.
Your braking on the left wheel will pull the car to the left (possibly
into oncoming traffic)and the slipping right wheel will not have enough
traction to overcome.
The driver will have to compensate by releasing the left brake which is
the only one with traction and will be totally dependant on the limited
traction of the right wheel to try to straighten out the car.
I like the overall style of the car but as I see it, the steering
mechanism needs to be rethought. Or am I missing something here?

lithium battreies would be great in this car, and the car can hold a lot of
batteries. As for speed, the car can hold 2 11 inch dc motors that, and
two zilla 2k controlers(do the math) if I put them in the car,could rip the
tires off the car, but that would be to much for most people. The
maneuverability of this car is so much better than a conventional car its
amusing. Let me also remind you this car is not like any three wheeler you
have ever seen, even at higher speeds it turns quicker that a conventional
car, it also has a very low center of gravity. A writer from the Palm Beach
Post I gave a ride once wrote, gut wrenching turns. I will also remind you
this car is easy and fun to drive.

first hybrid turbine electric car over 30years ago. He was on the cover of
Popular Science, he approached Detroit with it ,but they wouldn`t get off
the dime. I don`t think its any different now. All steering and braking is
done by the rear wheels, if the electronic steering fails,and it has once or
twice, the car is easily steered by left and right hydraulic brake, as for
traction have you seen the size of those tires?
