I cannot be convinced that school buses driving on the highway, even in the right lane, with lights flashing on top, and behind and in front and beneath, is remotely safe when they move at 45 mph while traffic all around them moves at 70 mph. This cannot possibly make things safer all around. In the last two days I have encountered dangerous traffic conditions, once in the morning and once in the evening because of school buses going too slow.
Drive faster or get off the highway. Someone's going to get hurt. In an effort to make things safer for the kids on the bus, bus drivers ironically create unsafe conditions for everyone around them.
