He's taking amateur lines which means he's probably an amateur driver so I'm not surprised he didn't notice it.

Excuse the expression, but this guy got w**d while drivng this car.

Well.....yeah!That's kinda' the idea.:wink:

Nice find. It is nice to see something other than in-car footage on the track.

Harry from Dumb And Dumber!

Too funny!

This a little more encouraging.... & supports the supposition that most car reviewers know jack schit about performance driving.

This guy gets a lot more out of the car than the other reviewers,
despite his poor steering technique.

understeer? can someone please tell me what you guys are referring to?

From WiKi

Understeer is a term for a car handling condition during cornering in which the circular path of the vehicle's motion is of a markedly greater diameter than the circle indicated by the direction its wheels are pointed. The effect is opposite to that of the oversteer and in simpler words understeer is the condition in which the front tires don't follow the trajectory the driver is trying to impose while taking the corner, instead following a more straight line trajectory.
This is also often referred to as pushing, plowing, or refusing to turn in. The car is referred to as being 'tight' because it is stable and far from wanting to spin.
As with oversteer, understeer has a variety of sources such as mechanical traction, aerodynamics and suspension.
Classically, understeer happens when the front tires have a loss of traction during a cornering situation, thus causing the front-end of the vehicle to have less mechanical grip and become unable to follow the trajectory in the corner.
In modern race cars, especially open wheel cars, understeering is caused mainly due to the aerodynamic configuration. In this respect, the lack of a heavy aerodynamic load (downforce) in the front side prevents the front tires from gaining enough traction. At the same time understeer can be caused by having a heavier aerodynamic load at the rear end of the car giving the rear tires more traction than the front tires. Also, suspension balance should take into account the types of surfaces being driven - differing levels of friction in each surface influence the potential understeer behavior. Camber angles, ride height, tire pressure and centre of gravity are important factors that determine the understeer/oversteer handling condition.
Understeer covers several different phenomena, in particular, there is a big difference between linear range understeer, typically between 0 and 0.4g, and limit handling understeer, which is at higher lateral accelerations, and is what racing drivers are talking about.

Man - he's gotta lay off the marketing Kool-aid before he does these pieces. Lightweight - 3300 pounds is light?, KEWL color - Sedona red?. . . Oh man.

That was fun though, watching him get into the car. His excitement was contagious!

I laughed when he yelled out "Understeer? Go Faster!" and then hooted in joy while the back end drifted. Very entertaining!
