Solar over canals and reservoirs is a great idea, and the catchy name is floatovoltacis for floating installs on reservoirs. Solar roadways are an absolutely terrible idea. I think that car placement is still mostly bad idea but it shouldn't be thrown out yet. As PV gets cheaper and cheaper, the financial impediment disappears and it starts to make a small bit of sense. For a regular sedan, solar panels won't make a car completely autonomous, but one could fit at least 600W of cells, and if parked in the sun all day, that could generate 2-3kWh of power, which is 8-12 miles of range. Plug in charging would still be needed, but that extra bit of power could be used for temperature control of the battery pack or interior too, while the car is sitting in extreme heat in Phoenix, or outside a garage in North Dakota.
