Tony:

He said he will pay for everything so you don't have to work but you refused, saying you wish to work and earn your own money. When he has to drive you, he will take his most expensive car and flirt a bit with some of your lady co-workers.

Steve:

He put the motorcycle helmet on you, telling you to hold onto him tightly for the fifth time. He didn't drive quickly and drove more careful than usually. When you told him he can go faster, he said he won't because his child is with him and he doesn't wish anything to happen to you.

Clint:

He had to go somewhere near where your work is so he told you he will give you a ride. On the way offer, he made some jokes with you. When you arrived, he wished you luck and told you that he will come pick you up when you are done with work.

Natasha:

She was bored so she decided she might as well keep herself busy by driving you to work. As she drove you, she was so busy talking with you that she accidentally passed your work. When you said she passed it, she chuckled, apologizing before doing a quick U-turn making you curse and say that's not allowed here. She just shrugged and said nobody saw it.

Bruce:

He was nervous driving you because he was unsure what to talk about while you were both in the car so he awkwardly asked you if you wish to play some music. When he had to park, he almost hit another car, for which he apologized to you. 

Thor:

He wanted to so you reminded him that he doesn't know how to drive a car. He gave you a smile and said he can try. When you mumbled driving is not as simple as he thinks it is and you will drive yourself, he pout but nod and said okay.

Loki:

He can't drive... So he walked you. He wouldn't have done so but it was your first day to work and you were very nervous so he decided to walk you to work while assuring you everything will be okay.

Bucky:

If you need a drive, he will gladly drive you. Sometimes he can't because he has to go work, for which he will apologize and tell you that you will have to find another way to go. He likes to pick you up from work more because then you two can go to a diner and catch up.

Peter:

He just got his driver license so he wants to drive everywhere, even to the store that's just on the corner of the street. He doesn't even listen to you when you tell him you will walk to work or drive yourself, he will push you to the car, excitedly telling you that he will drive you and come pick you up.
