All 警车 encounters were in KwaZulu-Natal. Yes Swaziland

changed its name.  I forgot what it is called now.

In KwaZulu-Natal,  there is very few 高速.  Even the "national routes" can be very narrow and look like farm roads.  Actually they ARE farm / lumber production roads that go thru various plantations and lumber lands.   More than once my husband questioned me,  "You sure we should take this road?  It looks so narrow, does not look like a major route at all."  After a few times he realized those roads are primarily built for economic activities, NOT for tourist driving!  LOL.
