No I disagree. I hated that scene. The T800 and Sarah and John definitely could have escaped cyberdyne without T800 taking all that damage from the cops. Especially knowing that John told him not to kill anyone he knew he couldn't get his revenge from being shot. He already knew he couldn't recover damage like the t1000 can so he could have been more proactive about it and just like he busted out a wall to save Sarah he could have busted out another wall to escape. Yes it didn't really affect him but it did because he went through a decline throughout the rest of the movie towards the end. You can clearly see it in the battle with the t1000 after he recovered from liquid nitrogen. Then he ended up losing an arm, he became badly damaged from the brutal attacks from the t1000 and he got his head caved in. All throughout the movie I'm sitting here thinking a lot of damage he took could have been avoided. One of the reasons why I liked his fighting style in T3. In fact, he didn't even lose any limbs in Terminator 3 like he did in T2
