Well, it depend if it is the older model or the newer one. Most
newer amour vehicle uses steering wheel. Easier to drive, just like
an auto car.
In layman term, those so call 2 handles, are like 2 giant job
stick, except that they only move forward or back ward. They are
actually very simple mechanism and easier to manufacture. Both are
brake stick. One to to brake the left side and the other to brake
the right. If u wanna turn to the left, just pull the left stick
toward urself, hence braking the left more and the vehicle turn
left. If u wish to stop the vehicle, just pull equally on both
stick.
It take alot of strength for an e-brake, same as driving a bus with
no power steering, but worse when braking, coz most driver actually
have to brace their foot on the floor and used his body weight when
braking hard.
