I'm a pretty good cyclist, I commute every day, but even I would probably struggle to use a laptop whilst riding...
I mean, a bike has two wheels, if you stop holding the handlebars, you kinda...topple over?
On the flipside - cars make it pretty easy to use your phone (or heck, laptop, as you say).
I see drivers using their phones 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.
The CDC and NHTSA's has webpages devoted to this trend:

We're talking several thousand deaths and several hundred thousand injuries every year in the US.
