Does Tesla or Alphabet Have the Winning Approach to Driverless Car Technology? | TSLA, GOOG

Parkev Tatevosian, CFA•Sep 3, 2026

Summary

Parkev provides an analysis of the ongoing technological and economic battle between Alphabet's Waymo and Tesla in the autonomous vehicle industry. The core of the debate centers on Waymo's use of a redundant sensor suite (Lidar, Radar, and Cameras) versus Tesla's cost-focused, camera-only approach. Parkev highlights that Waymo is currently ahead in terms of testing and operational scale, providing 500,000 paid trips per week across 14 cities, whereas Tesla has a much smaller testing fleet and has missed several long-term deadlines.

From a financial perspective, Parkev examines the valuation risk and customer acquisition strategies of both companies. He notes that Alphabet has a significant advantage in marketing due to its existing billions of users. Meanwhile, Tesla possesses superior manufacturing expertise but carries a valuation that is heavily speculative based on future AI success.

TSLA: Tesla is pursuing a camera-only approach to autonomous driving to minimize costs, though it remains years behind its original schedule. Parkev warns that the company's valuation of 164 times forward earnings is incredibly high and assumes total success in the robotaxi market. If the technology fails or is abandoned, Parkev predicts the stock could crash by 50% to 75%.

GOOGL: Alphabet’s Waymo utilizes a redundant sensor suite including lidar and radar, which Waymo claims is necessary for safety at scale. Parkev notes that Alphabet trades at a much more conservative 22 times forward earnings, offering a more attractive risk-reward profile. Additionally, Alphabet can leverage its billions of existing users to lower customer acquisition costs for its autonomous services.

Parkev concludes that while both technologies have pros and cons, Tesla investors face significantly higher downside risk because the autonomous vehicle success is already priced into the stock.

Mentioned Stocks

GOOGL

Sentiment: BUY

Reasoning: Parkev views Alphabet as a safer investment compared to Tesla because it trades at a much lower forward price-to-earnings ratio of 22. Parkev argues that even if Waymo's autonomous driving success is mediocre, it will not have a massive negative impact on the stock price, whereas Tesla's valuation offers no such margin of safety.
