People do some really silly things in front of trams. I guess quite some credit is due to tram drivers for saving many people from the foolishness of their actions. What car drivers, and pedestrians for that matter never think about is the impact on passengers inside the tram when the driver has to brake hard to avoid an errant motorist or pedestrian.
I think a front facing camera on trams would be a marvellous idea for Melbourne's trams. It is proven technology already as you can see by this Youtube clip. Its pretty hard to believe how stupid the motorists are in this clip. The edge of the tram line is clearly defined with humps and line marking. Although the clip is not in English, it is from the US of A.
