If it were to happen in North America, the traffic fatality rate would rise, with most of the newer casualties coming from truck/microcar accidents in rush hour/bad weather. Indeed, a sizable casualty list could result from midday interstate driving: suppose traffic were moving along normally on an interstate (say, ~65 mph) with a tractor-trailer in the rightmost of three lanes and the other lanes well populated by microcars. The divider between the two directions of traffic is a jersey barrier: one of those uncompromising concrete walls. Now suppose the tractor-trailer has a sudden, precipitous blowout on the front axle. That could yield loss of control of the truck at speed, causing it to swerve uncontrollably into the other lanes, wiping out multiple microcars before finally coming to rest, likely on its side with a couple of microcars trapped underneath.
