> This tram (and others) was recently installed with a new camera on the front that lets the tram know about its surroundings.

In fact, 2x no.

1. Just 2 trams (and you made a photo of both, thanks!) as a project or test without charge for De Lijn. Don't expect they will pay for this or make changes on the existing trams.
2. You can compare it with sensors, which you have now on every modern car. These sensors see (...) the dangers and give warnings and can brake. This system exist (for cars) since long and my experience is so-so, with my former and current car. With my former car, at one moment when I was driving on the highway, the car stops from +/- 100 km/h to 0 km/h... for nothing and no reason. It was quiet and very close to a parking place... With my current car, now and then all the warnings start "carefull accident is coming" without any reason... Is such system usefull for a tram in a city?

This system (for trams) is a project from an university and offered free of charge to De Lijn.
