This is my first vehicle with a touchscreen, and I was worried that it’d be a pain to use.

My 10 year old car has a monochrome dot matrix display that loses a good number of pixels when it gets hot out.

Accumulation of water or snow obstruct the radar. Actually a car with no camera would report exactly that just from radar readout alone, since it can detect worse signal-to-noise due to too much reflection in its readings.</text><parent_chain><item><author>SoftTalker</author><text>&amp;gt; Cruise will also disengage in heavy rain or snow&lt;p&gt;That’s what it should do, honestly.
