I see at least three things to talk about. Do you see more? Scroll down.

Comma splice. Change that comma to a semicolon or make this into two separate sentences. (I don’t think a comma-conjunction to make a compound sentence would work here. But there is another option with complex sentences. See below.)
Change like they own the road to as if/as though they owned the road. While like is fine in sloppily informal English, aim higher and do the thing properly: Don’t use like if what comes after it is a clause. Use as, as if, or as though. (Which normally also means the subjunctive mood.) How do you know it’s a clause? A clause has a subject and a related predicate. Do you see that above? I do: …they own the road. I see a they (subject), and I see an own the road (predicate).
Add a sentence-final period. Don’t be a lazy shit.
Possible rewrites:
Took me thirty minutes to get around them; cyclists really feel as if they owned the road.
Took me thirty minutes to get around them. Cyclists really feel as if they owned the road.
There’s one other possible change:
Took me thirty minutes to get around them; cyclists really feel they own the road.
This last change means there’s an implied that, a subordinating conjunction. The sentence also becomes a complex sentence, i.e., a sentence with an independent and a dependent clause. This in turn means no need for the subjunctive mood.
[with the that visible] Took me thirty minutes to get around them; cyclists really feel that they own the road.
As for whether to write thirty or 30… we’ve discussed writing out numbers before.
And remember that like/as thing. Like is not a subordinating conjunction, so don’t use it to introduce subordinate clauses.
WRONG (INFORMAL): Like I said…
RIGHT (FORMAL): As I said…
WRONG: Say it like you mean it.
RIGHT: Say it as if/as though you meant it.
WRONG: Don’t act like you own the road.
RIGHT: Don’t act as if/as though you owned the road.
Like is okay as a preposition:
• Why can’t you follow the rules, study hard, and think logically like Alfredo?
• Try to make better life-choices, like now, in this situation.
• The coral looked just like a brain.
• Don’t just sit there like a goddamn mushroom, idiot! Get off your ass and move!
The word as (by itself) can also be multiple parts of speech. See here.
