Hitting the kerb should not cause an accident at 40 mph in a not very sharp corner...
But these are not 'normal' kerbs. These have a slanted edge.
Hit them with a front wheel then it will make it steer into the kerb and climb it.
That can easily flip a car as small as an old Ibiza if the shocks are lame.
(Maybe the Ibiza had no power steering. In the 80s they definitely hadn't)
Too many uncertainties to judge - but poor kerb design may have contributed to the accident.
