Tesla Batters Rivian in Self-Driving Test

A major TV network put Tesla's FSD head-to-head against Rivian's new Autonomy+ system on real roads, and the gap between them revealed something unsettling about where the entire self-driving industry actually stands.

CNBC matched Tesla’s (NASDAQ: TSLA | TSLA Price Prediction) FSD (Supervised) against Rivian’s (NASDAQ: RIVN) Autonomy+. The analysis also measured other “AI” self-driving systems. The Tesla product bested these. But the primary head-to-head comparison was between Tesla and Rivian.

Rivian has counted on Autonomy+ to boost sales in a very difficult US EV market.

Rivian offers its system for a free trial, after which owners can then pay $49.99 a month or “own” it for $2,500. It drives hands-free if there are painted or dotted lines on the road. That alone is a major drawback. To change lanes, the driver has to turn on the blinker. According to the Rivian website, two important features are available now. These are automatic parking and an “on-ramp to off-ramp” service. (I own a Subaru; the balance of the features are about the same as what I have.)

Looking over all the Rivian features, CNBC wrote, “But it’s still playing catch-up to Tesla’s FSD when it comes to non-highway driving and point-to-point driving, where a vehicle is designed to navigate itself from start to finish.” Tesla’s product costs $99 a month.

Tesla leads for several reasons, but most importantly, it operates well in the dark and on unmarked roads. (One of my sons has the latest features on his Tesla, and the operation is seamless on the 50 miles of back roads between his house and mine.) The CNBC reviewer wrote, “During my drives in the Model Y, the vehicle was essentially controlling itself for multiple hours and dozens of miles without intervention on highway and non-highway roads.”

What do the test results mean? While Tesla leads the industry, none of these products has been approved for driving without drivers paying attention. This may mean full approval will take years. That means no matter how good the Tesla is, the driver does not have true independence. Teslas have been involved in several visible accidents that have been widely covered in the press. This has hurt its image and reminded people that supervision is still needed.

Some evidence suggests that the only vehicles that have made the full self-driving transition are in China. Tesla, Rivian, and the other companies that sell cars in the US are lucky. Those Chinese cars are kept out of the US because of tariffs.
