I think the military Humvee was designed to take on and drain rapidly to maintain tire contact with the riverbed during crossings. If you plan to drive out of the water anywhere but a boat landing or rocky beach, that traction is important to prevent simply bouncing off the bank. I like the...

In sudden zero visibility it doesn't need to tell the difference. It just needs to go 15mph to reduce closing speed from the idiot behind me and maintain steering ability, stay between the centerline and shoulder best it can according to GPS, and dont hit anything big. Sign or truck, I don't...

Take conservative action to narrowly avoid the worst case scenario. If you've done everything below and still cant decide, apply the brakes. You don't trust any sensor fully, they are given variable weight based on trends. If a large portion of camera image has been white or black over the...

I've had to pull over and seek shelter under an overpass in severe rain with hail due to lack of visibility. Same in snowstorm whiteout conditions. It makes you a sitting duck target for anyone 'brave enough' (dumb enough) to keep doing 70mph unable to see their hood ornament. I would pay...

I want to identify those and correct my assumptions, but I cannot pick them out from your reply. Actually, many of the facts you state are the reasons for this idea in the first place. The intent of this thought experiment is to explore an alternate type of reusable first stage. Like any new...

If you care about which compartment something is in, you can see where the yoke is on that particular vehicle. When speaking generally about a feature in that area, without a specific vehicle to reference, it is probably more relevant whether it is near driver or near passenger, not so much the...

So there is this air pressure/vacuum cannon. It could be made much larger. Concorde can fly 2,179 km/h and 18.3km high. It has hydraulic systems to reconfigure the nose. Pressurized fuselage. Cruises at altitudes where air pressure is quite low. Fuselage internal length 39.32 m...

This is an early Model S drivetrain unit https://www.teslarati.com/wp-content/uploads/2015/11/Tesla-Model-S-Drivetrain-Unit.jpg Later models acquired structural ribs and other features, but the dual cylinder layout reveals a clear forward looking design intent. The inverter does not need to be...

I've still got my old Logitech momo wheel.

Its clear. Probably a 4 bar linkage with air actuator.

The curb is a good idea. It got me thinking there could be an inflatable actuator on the bottom edge of the ramp that helps push it up. The steepness is really only a problem when we try to accelerate up too fast. We could drive onto the bottom part of the ramp, wait for the inflation to...

Thank you for engaging on these challenges. Lots of good ideas in there, still processing. https://eksobionics.com/ is a bit of what is available right now if you want to feel like Ironman. If the chair could lower me enough to pick up a dropped pen and raise me enough to do dishes and cook...

Off the top of my head typical powerchairs are 24"-28" wide. 17-24" seat height, Seated height to top of head 48-60", total length about the same as user seated height. 10-13" tall drive tires, 5-9" casters, wheelbase 26-50" Rehab chairs are 250lbs to 450lbs. Regular chairs support users up...

For someone mobility challenged, the potential to get in your FSD vehicle by yourself, have it take you to a destination, and get out by yourself can be life changing. Lets discuss what it will take for Tesla to build the first vehicle equally accessible to abled and disabled solo operators...

If you only need one voltage, why would you use multiple converters? Just more current? How about more capacity instead? The problem solved by modular converters is accommodating a few different accessories that require different voltages using a single part number. Maybe the solution is to...

That gentleman and I share almost every feature you describe except I can still walk briefly and use my arms. It makes a universe of difference, but I partially share his point of view. Any chance for an outing is treasured. I'm sure he appreciates it deeply. Wheelchair accessibility as a...

A 24v power tap on cypertruck would be useful for charging a power wheelchair as well. We're looking at CT as a WAV because of the powered ramp and possible midgate to slide off the wheelchair and into the drivers seat. Might be nice to charge up the kid's hoverboard too. What if the 12v tap...

I suspect it takes more for you to really be in trouble than the rental car warrior that wants to see what this off roading thing is about. Offroad FSD is probably for them (the rental companies), but your input would be needed to make it better.

These ones interest me. Central Tire Inflation System gets a big thumbs up. If you have onboard compressor stock, CTIS should at least be an option. SLAM (simultaneous localization and mapping) is already implemented, but we need the ability to supplement with additional map sources...

A plastic barbie power wheels jeep with a 12Ah battery can operate a Warn Zeon 12s winch briefly and pull itself out. An RV with the same winch and 900Ah battery bank might not. It isn't about being able to operate a winch, its about being able to get the job done. Figure out what the vehicle...
