My mistake, 'random' was probably not a very good choice of words here. :)
I meant that the engineering restrictions for roads and road vehicles are somewhat more relaxed than that of train routes. Curves can be banked, and larger gradients can be dealt with more effectively than that of a railway track where no such flexibility exists. Roads can be banked to higher angles, and can deal with much larger gradients easily while still maintaining the high speed requirements. So, minor realignments etc are technically as problematic for roads as they are for rails.
