Can cops arrest me if they have no evidence that I was the one driving?

I was at the bar. I moved my vehicle, I went on the roadway for one second. I stopped in front of my parking spot and squealed the tires. It was not fast. I backed up and pulled it into a parking spot. I hopped out and started to walk away. A cop grabbed me and tried to throw me back in the vehicle. I sat down. Witnesses said I was not driving, we argued. Another cop showed up and interrogated me. She said I must know all the right people, threw her hands up and told the other cops I got nothing. As she walked away, I took a one shooter, drank half and pitched it. She came back and told me I was under arrest. People were screaming I didn't drive I was at the bar. So I'm in the cruiser now. They asked the bar owner for video. He said I wasn't there. So they took me in. They told me the only reason I was arrested was because the bar owner said I wasn't there. Liar. I walked into pee in my cell. I blew a point 08, she said you're not even drunk what else are you on. I said mad. Surprised again when I had no record. Told me remember both officers have to show up. I said what about you, she said no. I tried to call my appointed lawyer, no call back, didn't have my file, he said. I got to court and he tried to make me plea. He said he would be at home sleeping and I will be in jail. Judge would give me reckless endangerment.
