I suspect that going from 5 cents to 10 cents will not have much effect on people returning bottles but may incentivize street collectors a little more. Inflation has reduced the value of returning bottles by about 84% as the inflation adjusted value should be nearly 30 cents. Going to 10 cents means recycling have about 1/3 rd the original value or incentive. 
The real value of a bottle or can should include the "cost" of not recycling. Hard to determine I suppose, but it would include the visual eyesore of litter, long-term accumulation as they don't break down, threat to wildlife, loss of resources (metal, glass and oil) and safety hazards. As it is now is imperfect capitalism.
Walk or bike along rural roads and you see cans and bottles everywhere. These are almost always booze containers, likely discarded  by motorists to avoid open container fines. That implies drinking  and driving.
 Could this be rural folk defacing their treasured countryside?
