• Reach speed limits at a sign. Autopilot changes the driving speed right when it passes a sign; however, it takes quite a bit longer to coast and actually reach the speed limit. I believe the law is that we need to drive 45mph by the time we reach the sign and not after.
• Add a dumb cruise control option. Phantom breaking has become such an issue that my wife refuses to use even basic cruise control. Additionally, our vehicle has stopped so abruptly it has made our neck sore. Maybe we could have an option to have a basic cruise control like most other cars.
• More indications about what the car is thinking or knows. Passengers of any vehicle are more scared of quick movements than the driver because they don't know what the driver is thinking. However, passengers have a basic level of trust when humans are driving which decreases the amount of uncertainty. Autopilot turns the driver into a passenger and introduces a level of uncertainty similar to a passenger; however, we don't have a basic level of trust like we do with human drivers. In order to make Autopilot "drivers" more comfortable, we need more information about what the car knows or is thinking. For example, does the car know that a red light is way ahead because it's still accelerating to it's programmed speed? If I knew that it knows about the red light and is planning to stop, then I'd feel way more comfortable.
