Ten years from now
Assumption 1) I'm still alive and have a driving license
Assumption 2) the roads we presently use aren't pot-holed and overgrown with weed trees
I think the biggest change will be all bio-fuel - petro-fuel will simply price itself out of the market for two reasons
1) cost of production and shipping is way high
2) continuing pressure to get to zero fossil carbon emission
and possibly the use of petroleum will shift to high value products when cheap bio-fuel is available
