I knew I was on the right track when the salesman told me that the customer who just preceded me for a Tesla (TSLA) Model X 90D SUV was the Golden Bay Warriors star basketball player, Steph Currie.

Well, if it’s good enough for Steph, then it’s good enough for me.

Last week, I received a call from Elon Musk’s office to test the company’s self-driving technology embedded in their new vehicles for readers of the Diary of a Mad Hedge Fund Trader.

I did, and prepare to have your mind blown!

I was driving at 80 MPH on CA-24, a windy eight-lane freeway that snakes its way through the East San Francisco Bay mountains. Suddenly the salesman reached over a flicked a lever on the left side of the driving column.

The car took over!

There it was, winding and turning along every curve, perfectly centered in the lane. As much as I hated to admit it, the car drove better than I ever could.

All that was required was for me to touch the steering wheel every five minutes to prove that I was not sleeping.

The cars do especially well in rush hour driving, as it is adept at stop and go traffic. You can just sit there and work on your laptop, read a book, or watch a movie on the built in 4G WIFI HD TV.

When we returned to the garage the car really showed off. When we passed a parking space, another button was pushed, and we perfectly backed 90 degrees into a parking space, measuring and calculating all the way.

The range is 255 miles, which I can recharge at home at night from a standard 220-volt socket in seven hours. The chassis can rise as high as eight inches off the ground so it can function as a true SUV.

The “ludicrous mode,” a $10,000 option, take you from 0 to 60 mph in three seconds. However, even a standard Tesla can accelerate so fast that it will make the average passenger carsick.

Here’s the buzz kill.

Tesla absolutely charges through the nose for extras.

The 22-inch wheels are $5,500, the third row of seats to get you to seven passengers is $4,000, the premium sound is $2,500, leather seats are $2,500, and the self-driving software is $2,500.
