OKay, so your husband- the guy who bought the car- is working really hard. That is a little sad. But the ending is too over the top.
Over the top… or down in the chasm?
And how do you know he bought the car? Or that he’s working?
That is what the ad is all about- he has so much work to do (he even says that at the start) he cant take his eyes off his device.
I don’t believe he’s actually “working.” YMMV.
And who bought the car?
I mean, of course the man bought the car. How would a woman get enough money to buy a car? How can a woman make a decision like that? 
He was working, seems like it is their only car, so who knows? She also seems surprised at being asked to drive. Would she act like that if it was her car?
We don’t know, from the limited information provided in the ad. But I suggest that it could be their household car and that he usually prefers to drive, so she’s a little surprised when he tosses her the keys. I just don’t buy (heh) your flat assertion that he bought the car.
It was a WAG based upon how they talked. However, Okay so they go on a drive and he needs to work rather than enjoy the view. is anyone saying here that it is okay to murder someone over that?
In the context of a minute-long ad, and given what a jerk he was, yeah, it’s understandable and even funny. YMMV. In the real world, she should explain why she’s unhappy with him and maybe even break up with him, but kill him? No. Of course not.
Well, not to overthink it, but she did say to him in one of the little scenes “We’re here.” So, I’m assuming there was a destination, and he ignored everything including the fabulous scenery there and back. If he was going to be such a wet blanket, he should have just stayed home.
Okay targets new ad
is kinda nice, and Donovan is always nice to hear again-
But did the ad guys actually read or listen to all the lyrics?
I can make like a turtle and dive for your pearls in the sea, yeah
A you-you-you can just sit there a-thinking on your velvet throne
'Bout all the rainbows a-you can a-have for your own
When you’ve made your mind up forever to be mine
