Perhaps that seems OTT, but I can imagine it being quite good on an unlit motorway, when the whole family has to get out.
I'm afraid that is actually a classic example of actually overestimating the safety benefits of high-visibility clothing. Someone driving a vehicle with the headlights on a standard dipped setting on an unlit motorway at 70mph (or, more than likely, faster) will not have very much time at all to react to someone wearing EN471 Class 2* high-visibility clothing, and only slightly more for Class 3 clothing. The retroreflective surfaces are not adequate visual protection for walking or standing on a motorway. There is a very good reason why recovery vehicles and HA patrol vehicles can light themselves up like Christmas trees (not literally!), and why there are VMS signs which are frequently used to warn drivers miles in advance of incidents. Drivers on motorways need a long distance to react to problems, and many don't do so properly at all - the number of times I see drivers passing lane closure signals in the applicable lanes actually infuriates me.
If you have such clothing near you when you break down, then by all means wear it, but rather more important would be exiting the vehicle to the left (where possible) and standing behind the crash barrier, once the hazard lights have been turned on and the handbrake of the vehicle secured.
*Most sleeveless high-visibility vests should comply with EN471 Class 2 - adequate visibility for roads with speeds up to 40mph in good conditions - and these are what most non-professional drivers equip themselves with.
