5/5, 10/10, 100/100.
Before I met Sam, I could only drive around factory roads where no cars were around. With Sam's instructive teachings of driving mindsets and techniques, Sam and I drove around the city with no fear and full of confidence. Most importantly, he was constantly aware of the road while teaching at the same time, and was always ready to brake/accelerate when you made mistakes. He is a very professional, helpful driving instructor, and is also a very humorous and wise man.
