Carwise, I've no personal experience driving them.  But I am gradually working 
on my aunts MG which 
has these type wheels on it (54 MGTF).  I have noted a fair number of broken 
spokes on each wheel. 
Roughly 3-7 per wheel.  Each broken out at the rim.  Would I be willing to 
drive it that way?  Yes, 
provided we're talking about get it running and gingerly drive it up and down 
the farm lane.

I do not think it likely, or even particularly possible, to have the wheel 
experience a 
catastrophic failure because of its design.  But if you neglect the wheel, 
problems would progress 
and could snowball.  So, check your spokes often.

Engine power isn't a particular problem with spoke wheels.  That's coming from 
a motorcycle 
background.  I've had spoke wheels where you had to screw the tires into the 
rims to keep them 
attached because of the engines power.  And had the engine rip sprockets apart. 
 The wheels would 
hold up fine, as long as they were maintained.  Let all  the spokes get loose 
and dump the clutch, 
well, I think you can see the difference.

It's turning that's death on spoke wheels.  Especially cars.  Then you're 
putting all kinds of 
horrid forces on the spokes, and are far more likely to snap them.  Vehicle 
weight is hung from the 
top spokes, spread out over quite a number of them (half roughly).  Engine 
power is distributed 
over half of them as well (those that are rotating backwards).  But when you 
put the side load, 
only a very few spokes are taking the load.  If the tension isn't balanced 
right, you can literally 
have one spoke taking the load at a given moment of tire rotation.  And that 
will snap a spoke 
quite rapidly.
