If a gallon of gas ends up at $10 ten years from now, how much do you think people will complain about having to wait an hour to recharge their electric car? Not much I'm guessing.

Natural gas and petroleum are about as similar as the hydrocarbons of corn and cherries.
Coal, petroleum, and natural gas are three large categories of energy hydrocarbons. If gas is cheap relative to oil or coal, then at the margin, some users will shift to gas. Prices of energy hydrocarbons will be correlated, over the long term.
Then, as coal, oil, and gas are all depleted (with their own separate peaks, perhaps), their prices will increase. Foods like corn which have many dependencies on low-priced energy (farm equipment, fertilizer, drying, and transport), will come under increasing upward price pressure.
Corn is used in perhaps a quarter of food SKUs in American grocery stores, so won't a lot of food prices go up as energy prices go up, as a consequence of peak oil (or coal or gas)?
No one uses oil to generate any significant amount of electricity, most gas turbines are powered by natural gas, since it's cheap and plentiful. Gas turbines are only used to peak load not base load since coal is even cheaper than natural gas.
Most people spend more in fuel getting their groceries home than transporting them to the store. Food miles should be calculated by the distance to the grocery store from your home.
Tesla's looking good though, so there's hope.
That's the fundamental problem.
This thinking generally leads people to miss OP's point, which is that the world will never run out of oil. Price will always fluctuate to meet demand (so long as we let the market set the price).
If you want to open an oil field or a refinery you need billions of dollars and a financial projection that says the oil will stay at $X dollars for at least Y years.
Since most people aren't convinced that oil will stay at $110 dollars for the foreseeable future they'd rather not risk billions of dollars.
If you can accurately predict oil prices stop reading hacker news and open a commodities account.
The hydrocarbons that become economic at higher oil prices fundamentally cannot be produced as quickly as conventional reserves. It's a matter of permeability. Not a matter of economics.
Also, I'd wager I'm far more aware than you think of the investments required to explore, develop, and produce a prospect. (I know nothing about refining, though.)
Peak oil also depends on consumption, with cars like Tesla coming out we'll see a sharp decline in consumption over the next 20 to 30 years, at $300/bl a Tesla starts to make a lot of sense.
The world will never run out of oil, its price will simply continue to increase until other alternatives become economically viable, as those alternatives become viable economies of scale and capital investment will make alternatives that much better.
