You cited a single example of somebody using their phone on a bike, several years ago - and yes, I agree, that was a pretty silly risk (and I hope that person is OK, and didn't do it again).
How often do you see a driver of a car using their phone?
I see it several times every single day in Sydney. I'm pretty sure most people would be lying if they told me they didn't see it either.
Heck, if you want stats - sure, here's the CDC and NHTSA's info on distracted driving:

Car drivers often don't like to be confronted with how bad a driver they are - but the statistics don't lie. We as humans are shockingly bad at driving (and I drive as well, and I'm well aware of my limitations).
And regarding your SUV vs bike example, may not happen often? I think that's stretching the rules of incredulity. I'm not going to make any assumptions about your background (e.g. you may not have a technical background). - and I don't have a physics background either - but I believe the basic equation is:
F = m * a
So you take a 2,000 kg SUV.
And a 8 kg bicycle, combined with a 65 kg person = 73 kg.
Even if they were travelling with the same acceleration (doubtful) - the SUV would impart around 30 times the force on the cyclist versus the other way.
