Electronic Thermometers Glitch All The Time

 A couple decades ago, some meterologists were admitting bluntly that electronic thermometers simply did not work correctly; and it's easy to see that they still do not work.  Today, the thermometer in my car suddenly increased almost ten degrees within seconds while driving down the road (usually it decreases while driving due to the cooling effect of air passing over the car at high speeds), and the thermometer at my house was showing an even hotter temperature (hence even more inflated). The various temperature readings from my town cited by the "Weather Underground" site often vary by ten degrees, even the ones that are within a few blocks of each other. I'm old enough to remember mercury thermometers, which had less variation and none of the crazy spikes that electronic thermometers are plagued by.
