I think you missed my point, he said "Some of the worst roads in the world"
Those types of roads are not condusive to being a "Million Miler"
BTW, I do think if you log more than 600 miles in one day you've just thrown up a big red flag to the DOT because you're not allowed to drive more than 10 hours a day (You may work 14 hours).
Not only that, Jeremy's time in the sandbox, (for which I salute you sir ) both take away time from racking up miles unless you've been on the road for a long time.
11 hours driving time now but subject to change
