I have thought the same multiple times. I think the problem might not be super simple to solve through updating vehicles. You need to update infrastructure globally (and thus you need coordination between multiple different agencies), then you need to implement the solution at both airport and vehicles level. That's a lot of work. In case of LATAM the Airbus hit a fire truck (which would've too required such a solution). In case of the Linate air disaster, such technology would've had to be implemented on a very small Cessna Citation model. Maybe the updates need to be implemented at the airport level alone, quickly signaling controllers of possible violations/conflicts, and in fact most major airports have both ground radars and clear ground signals to avoid these incidents. But it's still impossible to avoid these issues as these errors may happen in a matter of very few seconds thus not giving enough time to react to any of the involved parties.
