Tesla's (TSLA) highly anticipated robotaxi event is on Thursday, and Barron's associate editor Al Root joins Asking for a Trend to break down what investors can expect from CEO Elon Musk.

Root points to five things investors are expecting from the robotaxi event. First, there will be a physical unveiling of the robotaxi. Second, investors want to hear about safety data. Next, Tesla will likely touch on its business model, discussing everything from licensing to the size of its robotaxi fleet. The fourth point investors will be looking for is a launch date.

Finally, Tesla could announce something extra. Root explains, "A lot of people think we'll see the lower price so-called Model 2 that's due in early 2025, maybe that will make an appearance. And maybe an update about the robot called Optimist."

Root also compares Tesla and Waymo's self-driving vehicles. While Waymo has built driverless vehicles and took a modest approach to its rollout, Root notes that Tesla is instead focused on improving its driver-assistance software to turn vehicles into self-driving cars. "Now, Tesla argues, 'We've got millions of cars giving us data. We have billions of miles driven with full self-drive on.' Yet, they've never done a single official autonomous cab ride. Waymo has," Root tells Yahoo Finance.

He continues, "So it's sort of like, you tell me, which approach do you like better? One feels a little safer. One feels a little more Musk-ian. And that's the way Tesla has gone."
