advertisements pasted on them

[Kumarc]

Nowadays, many buses in our city are seen with advertisements pasted on them.
Nowadays, many buses in our city are seen with advertisements. (Without "pasted on them" )
Nowadays, I witness many buses with advertisements running in our city.

Can we use these sentences in everyday's communication?

1. Nowadays, many buses in our city are seen with advertisements pasted on them.
2. Nowadays, many buses in our city are seen with advertisements. (Without "pasted on them".)
3. Nowadays, I witness many buses with advertisements running in our city.

Can we use these sentences in everyday's everyday communication?

If by "everyday communication" you mean "informal speech", I'd say they're all a bit too formal (particularly the one with "I witness"). If I wanted to say this about London, I'd say something like:

There are loads of buses with ads on the side in London these days.

I'm guessing that it's a relatively new thing there. Why do I say that? Well, here in Charlotte it's so common that nobody would think it's worth commenting on.
