Poor Man's Autopilot - ES300h
Thanks to a 16.9oz bottle of Aquafina, I may or may not have driven most of the way from Philadelphia to Michigan entirely “hands free” while using cruise control (*with minimal exceptions*).
Theoretically...by wedging an “unopened” bottle of Aquafina into bottom opening of steering wheel, it removes need for intermittent driver contact with steering wheel as required by system alerts. The pressure and weight of water bottle tricks system into thinking your hands are on the wheel, therefore doing the steering for you “hands free”.
*Couple of theoretic caveats*
- Highway speeds preferred to avoid “ping-pong” effect observed at lower speeds
- Avoid using on curvy highways as system aided steering cannot hold on sharper curves (mountains sections)
- Lack of visible lane markers detected by system will require driver input (i,e. Construction zones, poorly painted line makers, etc.,)
- Initiating a lane change will require driver input
- Don’t allow bottle to protrude too far through wheel as-to interfere with turn-signal, etc,.
- Remove before exiting highway or making any suddenly rotations of steering wheel as above scenario could happen (don’t ask how I know)
- Always be alert for any steering or braking input
- Bottle must remain “unopened” as it needs bottle pressure to override sensors - need to use skinny version 16.9oz bottle found in 30 packs at most stores.
- Tried using tennis ball for less bulky alternative but I couldn’t replicate the same scenario

I'm afraid I must agree with concerns posted earlier (if you are indeed serious). These lane keep assist technologies are only intended as an aid to the driver, not a replacement for the [driver/common sense]. I couldn't imagine trying to subvert the car's system because it is too much effort to keep my hands on the steering wheel. When I drive, it is safety first and I'm afraid this does not meet that criteria. I am hoping you were just kidding.

I've seen posts on the CL boards from people who trusted features like lane centering assist and all-speed cruise control more than they should have and who ended up in collisions.
If people want to risk their lives or well-being, I won't deny them that right, but I do have an issue when people think that their right to do so extends to the point that it risks the life and safety of others.
I have no interest in using any form of auto pilot, and I strongly believe that it should not be legal to use autonomous driving on any public roadways. I may re-think this only after NASCAR starts to equip vehicles with auto pilot and they can successfully complete a 500 mile race without even scraping fenders with another car or the wall.
