[OSRM-talk] Preferring motorways for a route

Emil,

I think the question is more along the lines of "How would one change 
the car.lua to make ORSM prefer highways?"

For example, should one increase the speeds on highways and/or decrease 
the on surface streets and feeder roads? This has the side effect of 
then not reporting accurate times.

You can not simply remove the other segments because of the obvious 
impact of that.

So giving some guidance on the strategies for doing this would be 
helpful. I've seen this question come up multiple times in the past 
month, maybe adding and FAQ page to address some of these issues would 
be helpful.
