1) Мы ехали в зоопарк вчера. (Describing the process of going to the zoo. But the sentence is incomplete. Actually it requires some extra information. For example: Мы ехали в зоопарк вчера, когда пошёл дождь/когда ты позвонила. -- We were going to the zoo yesterday, when it started raining/when you called.) No matter if they arrived there at last or not. 2) Мы поехали в зоопарк вчера. (We went to the zoo yesterday.) But you can't be sure they arrived at the zoo or not. Maybe it was closed yesterday. They just went to it. 3) Мы ездили в зоопарк вчера. (It's more like: We were at the zoo yesterday but not completely the same) Now it is more probable they finally get to the zoo. But still there can be reasons for not entering it. To be sure they were at the zoo, you should say: Мы были в зоопарке вчера. 4) Мы поездили в зоопарк вчера (Incorrect). To indicate they were going back and forth -- Мы несколько раз ездили в зоопарк вчера (We went to the zoo several times yesterday). You can use form "поездить" in the sense of travelling for a long time: Поездить по стране, по свету -- travel through the country, been around the world.

From student to student: making a long story short, normal verbs have two aspects, motions verbs have three (not four), so: читать/прочитать: imperfective (progressive or multiple) vs. perfective (achieved and single) ехать/ездить/поехать: progressive imperfective vs. multiple imperfective vs. perfective So the decision making is: 1. Done with a result? YES: GOTO 2; NO: Use progressive imperfective 2. One time or one direction? YES: Use prefective; NO: use multiple imperfective It often helps me with basic motion verbs.
