Tesla is making steady progress and has reached a few new milestones recently.<p>They recently launched their Robotaxi service in Austin, and it seems to be as good as Waymo or better. <a href="https://youtu.be/RcaBZenrCCs" rel="nofollow">https://youtu.be/RcaBZenrCCs</a><p>They also recently autonomously delivered a car to a customer’s apartment straight from the factory line. <a href="https://youtu.be/lRRtW16GalE" rel="nofollow">https://youtu.be/lRRtW16GalE</a></p>

<p>>but I’m more so pushing back on the added cost and complexity of human elements NOT required by the built environment<p>Am I understanding you correctly that you would want something that still had cameras at head height, but simply didn't have the head form factor? And perhaps had 4 arms for some tasks that it would benefit from instead of being limited to two arms?<p>If so, how many environments are you going to build robots for? And how does your total overall build cost increase with each different model you build?<p>Doesn't matter if it's simper in the end-design if getting there ends up costing you as much as it would to build a general purpose design in the first place.</p>

<p>No doubt, they are growing fast! And naturally they would make more than Tesla, since BYD makes more than just BEVs.<p>BYD's numbers often contain plugin hybrids (PHEV). So if you're trying to compare apples/apples, be sure to look at pure-battery EVs between the two.<p>Note 'electrified' from a different article from Barrons: "BYD delivered 206,089 electrified passenger vehicles in March [2023], up about 98% from the 104,338 delivered in March 2022. The March 2023 figures include 102,670 all battery electric vehicles and 103,419 plug-in hybrid models."</p>

<p>Hey, thanks for the detail here. Are you modeling in the increased IV due to upcoming earnings announcements? Do you hold anything in its run-up to earnings or through an earnings announcement?<p>Are you using OptionNet Explorer or OptionVue, or just your own software using the math you learned from your CBOE friend?<p>Interesting to hear about trying to use the Kelly criterion. I've always thought of it for bet sizing, which is tough since you never know your true odds (unlike counting cards, for instance).<p>For my own trading, I am having moderate success with selling premium on index options. I find it tough to make a meaningful amount of money while keeping blow-up risk low.</p>

<p>Interestingly absent is a discussion about bots abusing these booking systems. GDS' usually have a look-to-book ratio threshold with their airline customers. If the airline (via end users and bots on its website) does too many computationally intensive searches without booking a flight, that airline pays overages per their contract with the GDS.<p>You can imagine how a third party entity would make constant searches for seat and flight availability, spurred by all the possible permutations of airports and flight schedules. This flurry of activity rockets up the number of "looks" to the number of actual "books".<p>These third parties might be Online Travel Agencies trying to get around their own contractual limits with the GDS, or it might be companies that sell the schedule and fare data as competitive intelligence.<p>For now, the GDS' and airlines try to solve the problem with anti-bot solutions to keep contractual overages low.<p>If someone could instead solve the underlying structural problem (computational intensity? cost of compute? cost of running a GDS? offer free fare and schedule data to all?), they could probably crack open a multi-million dollar market opportunity.</p>
