Why do prices at the pump not reflect the price of a barrel of oil any more?  When a barrel was selling for $100 back in 2015 pump prices were at their highest at $1.40.  Now barrel's are selling for $50 and prices at the pumps are $1.15.  I understand that carbon tax has increased it a little, but if the government is putting another tax on driving then they'd better figure out better ways to move people via transit to reduce the amount of cars on the road.
