I clip in on both my road and utility bikes, on both rural roads and in the city. Just feels better to me, and I'm totally used to it, even in traffic and with lights, etc.

However both of my bikes have dual-purpose SPD pedals, and I use SPD shoes that look like normal walking/hiking shoes. That way I can use the platform side if I want to, or the SPD side, whichever I decide to use based on shoe choice. I use Shimano PD-A530's my road bike, and PD-M324 pedals on my utility cargo hauler bike.

It's nice to have options.
