With proper thick ice like we had a few weeks ago, it is as difficult to balance as riding on a tightrope.
Cars with 4 big wheels cannot grip on the stuff what hope has a bicycle?
With a short flat stretch, you can try and skill/balance yourself across with lots of concentration.
** But most roads have a slant **so you will be gliding sideways into parked cars, if you try to turn right to correct. BAM! You are down.
I myself went down three times during the icey stint, all riding straight ahead, and two of those times were on a mountain bike. It did not help in the slightest.
Which is equivalent to leaning. Just because there is ice does not mean "you are going down!".
