That's great. Consider yourself blessed. By comparison, I've has zero incidents in 10.5 years at nights, all over the country, but was able to avoid a few.
But that does not mean driving at night is not far riskier than driving during the day because the MoH finding say otherwise.
Additionally, the roads at night get a tad safer after 9pm, according to stats. By them most drunks are home.
I have been very fortunate with avoiding accidents as well, and I attribute it to my driving slow. I seldom go faster than 45 mph unless I am on the Autopista Duarte going to and from up North.
The rest of the time, I drive like an old fogey.
There are few accidents I've seen here that couldn't be avoided by driving slower.
