Tesla announced this week that a key component in its self-driving technology platform is about to move from radar sensors to optical sensors. Tesla calls its technology "Pure Vision." This is not exactly a shift to some higher level of technical know-how. Subaru has been using optical sensors to provide driver-assist features for much of the past decade. Armchair engineers and Tesla fans are now debating the shift in technology from one type of transducer to another. All I want to know is will the new sensor array stop Teslas cars from crashing into police cars, firetrucks, semi-trailers, highway barriers, and other static objects.

What Do Driver Assist Sensors Do?Stopping cars from crashing is one of the objectives behind the move to driver-assist technology. Tesla calls its two packages Autopilot and Full Self-Driving. Those names were chosen specifically to give you the impression that these vehicles can drive themselves. This begs the question; If they can drive themselves, even in certain circumstances, they must be able to see and avoid parked firetrucks with flashing lights, reflective tape and flares deployed ahead of the vehicle, right? Nope. Or they must at least be able to stop instead of crashing straight into the side of the largest vehicles on the road, tractor-trailers, right? Nope.

Does Teslas New Technology Prevent Crashes?For five years, Tesla vehicles equipped with the old technology have been regularly driving themselves straight into huge things anyone with eyes could see. Maybe this shift away from radar and toward optics is Teslas attempt to stop these seemingly preventable crashes from happening. Or maybe not. If not, then will Tesla vehicles continue to drive at high speed into emergency vehicles assisting motorists during highway emergencies? Although Tesla has not said if this technology shift will prevent the high-profile seemingly preventable crashes showering it with bad press, Teslarati reports that Elon Musk did say it would stop the phantom-braking reported by many Tesla drivers.

Are Tesla Crashes Common?If you are not up to speed on the types of crashes we are referring to, simply type Tesla hits firetruck into your browser. In under one second, your computer will provide you with over 7 million options to read more about this topic. The first story that comes up when I do the search is one from Car and Driver titled, NHTSA Investigating Indiana Crash Where Tesla Model 3 Hit Fire Truck.

Alternatively, you can type, Tesla hits semi. This search will show you about three million results. The top story on my browser is one from the Tesla-advocacy publication Inside EVs titled UPDATE: Tesla Crashes Into Another Semi: Federal Investigation Underway.

Whether or not an occupant (the word "driver" is so old school) enables a system inside of her Tesla or not is irrelevant. Driver-assist safety systems dont need to be turned on to work. All modern cars have advanced automatic emergency braking designed specifically to stop you from accidentally driving straight into firetrucks and semi-tractors. Yet, Teslas system seems to ignore these hazards on a regular basis and allow the vehicle to drive into them. How does that square with a company that advertises a product called Full Self Driving? Perhaps it doesnt, and perhaps the new sensors are an attempt to stop the seemingly preventable crashes.

How Can I Learn More About Unusual Tesla Crashes?The below list of prior stories may help provide background on the subject of Tesla vehicle crashes that were not prevented by the radar-based technology that Tesla has employed up to now.

Tell us in the comments below if you think Teslas technology shift will help stop future crashes of its vehicles into large, easy-to-see objects.
