4. There are safety issues regarding the earthing (grounding) and protection offered by street lighting circuits. In the UK they cap individual loads on these circuits to 2KW (9Amsp) to get around that cheaply. If you want to connect bigger loads, then you'll need to invest in compliant earthing, which may make the concept unfeasible.

Once all of those issues are addressed, the whole concept withers on the vine due to costs.
