i think they are phasing rumble strips out in some areas where freezing/thawing can become an issue because they retain water, and as for if you were to drift into oncomiong traffic:

i think roads are crowned (sloped) so that your vehicle (if you doze off) will drift towards the ditch (granted your steering is properly aligned and working properly...)
