It's not just our personal transport that's affected by oil price increases. These increases factor into every product we buy. They factor into our holidays (eg. plane tickets). They fuel inflation, thus fueling interest rate rises. All these things are connected. This is why the world worries so much when oil prices rise. It doesn't just mean €20 at the pump, it means a percentage increase in everything we buy, and every service we consume.
So yes, there is definitely a tipping point.
