Cruise Control when TACC Unavailable



When TACC is unavailable, allow manually set a fixed speed cruise control.


During normal TACC operation, the indication of this is the BLUE small analog speedometer.  When the sensors get covered in dirt or snow, the TACC capabilities are l disabled.

Offer the ability to turn on a non-TACC ‘old style’ cruise control when this occurs. This allows the car to maintain a fixed speed set manually.

On my old Merc the radar was disturbed by a lot of things, often disabling adaptive cruise control for the rest of the ride, Extremely annoying, and made me wish I picked the manual cruise control instead of the adaptive.

On my Model 3, it would be very welcome to have the option of falling back or selecting manual cruise control for whatever reason (hardware failure, snow on radar, personal preference).

Sorely missing this. We need standard cruise control to be available at all times.

In the winter my sensors are regularly convered in slush even if the roads are bare, salt melting the snow as if falls. No reason to not allow cruise control without sensors.

I agree with OP and the proposed mechanization with the display of a amber steering wheel is an logical and intuitive feedback to the driver.

There is a need for a basic control functionality when TACC is unavailable. On a recent trip to northern Sweden, the TACC quite often was unavailable due to ice and snow on the front radar - so the problem is present. It may be that TACC is always available in sunny California, but this is not always there case in cold and icy locations...!

You mean, if the autopilot won't engage, you can't even have normal cruse control? Why would they remove this feature?

I spend most of my time driving on roads that I'm pretty sure AP won't work on; I was thinking of buying a MS later this year (hence why I'm on sites like this) but if regular CC isn't going to work either I may reconsider. I just don't see what reason they have for removing that feature, my current car has it, as did the two before that. The roads I normally drive on have a fixed speed limit, very few sharp bends or corners that require slowing down for, and the lanes of the road are more than wide enough for large articulated lorries to pass; however, being in the country they have poor markings, and you're not supposed to use AP off the motorway anyway. I use cruise control almost all the way from home to work and back.

Frankly, for the cost of the car, I'm very surprised it doesn't have cruse control.

A much safer and more desirable feature would be a speed limiter like is requested here: or here:

I feel the need to point out that the OP has the TACC graphics confused with the Autopilot graphics.  The TACC graphic is the very small analog speedometer on the upper center left position whereas the Autopilot graphic is the steering wheel on the upper center right position.

You might persuade Tesla to allow for the operation of conventional cruise control when the sensors are dirty but I do not think it's likely.
