No people, therefore no civilisation
Even if we assume that the random teleport is being run by a "benevolent" trickster god or AI with safety settings on full*, this is not survivable at even the hunter-gatherer stage, let alone any more developed (and fragile) technology level.
The most obvious point of failure - actually tragic fatality - are the children. An infant that teleports randomly between 48 and 72 times each day is sooner or later going to end up stumbling onto something dangerous, or being overly exposed to bad weather, or bitten by something venomous etc.
"Oh, we'll protect them by having adults carrying them at all times until they are old enough to look after themselves," I hear you say, "The adults will all work together in shifts so that when the parents are sleeping then other adults will carry them." Unfortunately, that will not work - children learn to look after themselves by exploring their environment, rolling around, crawling, pulling themselves up on things and eventually walking. If they are constantly coddled then they will never be ready to look after themselves, even if it is practical to carry every infant 24 hours per day, 365 (or whatever) days per year.
For that matter, the civilisation will simply die of exhaustion. People need, on average, 8 hours of sleep per day, with greatly degraded health and mental alertness if they do not get it. These people can never get that, because they will be teleported out of their bed between 16 and 24 times per 8 hour rest period. Even in fair weather that is going to be uncomfortable and slightly dangerous. In a cold rainstorm or snowstorm getting teleported out into the cold multiple times per hour so the person (and their clothes and bedding) are soaked will kill them. I see it as unlikely that anyone would survive a prolonged period of bad weather. (Imagine the last time you were comfortably inside when the weather was foul outdoors, then imagine how you would be if you were teleported out into it every 2-3 times per hour for the entire duration of the storm.)
This is also ignoring the accidents that will happen in regular every day use when people are using tools such as shovels, picks, and cooking knives to suddenly find that they are swinging/stabbing/cutting somewhere other than where they started the motion, or that someone else has been teleported into the path of the dangerous tool they are using. With every person teleporting 20,000 times each year, one-in-a-thousand accidents will be happening daily even in a small family grouping.
Therefore, there is no need to even consider road safety, warfare or humorous/humiliating/unhygienic incidents concerning urination, defecation or fornication because this setting is unsurvivable for any length of time. Infants and children will probably die first, but the adults will not last much longer.
*When I say "safety settings on full", I mean that people are always teleported to be no more than a few centimetres above solid ground that is not on fire. If those settings are not applied and people are teleported to random heights in the air and/or over water or flames, statistically no one will last more than a few weeks.
