Probably will trap a Tesla with the production Autopilot build, but won’t work with FSD. Using a ring of cones would stop FSD though.

Elon Musk Shares SpaceX's Starship Raptor Production Plans To Colonize Mars By 2050

This engine needs to be 10X lower cost. Order of magnitude change is good reason for a new name.
What really matters is not yet another “advanced” rocket engine, as there are many such devices, but there has never been a cheap (<$1000/Ton-force) rocket engine. Not even close

Long chain hydrocarbons, like kerosene, have excellent volumetric energy density, but what you really want for rockets is best way to bind hydrogen, which is CH4.
Also, easy to make & store CH4+O2 from CO2+H2O, which are abundant on Mars.

So that's to say the more thrust you can get out of the bottom of the rocket, the more propellant you can get inside & the more it has potential to perform work. If they had a fixed volume, it would be more important to minimize dry mass, but here they can max thrust to max prop.

@elonmusk · Sep 18, 2021
Fully reusable rockets want high T/W to minimize $/ton to orbit, because propellant cost actually matters

It won’t be long until Tesla adds an option to enable Autopilot at the start of every drive
Instead of taking an extra step to get into Autopilot after putting the car into drive, it will take an extra step to get into manual driving after starting in Autopilot

In the latest FAA stakeholder document, dated September 2021, SpaceX revealed that Super Heavy is still expected to be equipped with up to 37 Raptor engines. This Raptor configuration was changed this year to a maximum of 32 Raptor engines according to Elon.

Ironically, yes at this time. FSD beta system at times can seem so good that vigilance isn’t necessary, but it is. Also, any beta user who isn’t super careful will get booted.
2000 beta users operating for almost a year with no accidents. Needs to stay that way.

Will Starlink be able to provide service for vehicles below AND above them? It’d be great to have high speed connection on orbit, finally!
Elon Musk
@elonmusk · Sep 18, 2021
Yeah. We’d use our Ka parabolics or laser links for Dragon, Starship or other spacecraft as soon as they got above cloud level.
