Look like very tiny stone chips and they should be able to hidden very cheaply with a smart repair - you may be able to attempt yourself with a kit.
I don't have first hand experience of this with Tesla's but Audi repaired similar on my car for £4 (touch up material cost) when it was in for its service.
I saw in your other thread you asked if you should fix before you sell, and I'd say that depends on who you intend to sell it to - when I sold my last car there were some small stone chips on the bonnet and the fact they were exposed gave the dealer confidence that they hadn't been poorly/cheaply hidden and I was honest about them, I don't think it affected the value of the car dramatically and it was one less thing to worry about.
These sort of things happen on cars so I wouldn't worry too much if you plan to sell soon, but they should be made good to prevent them getting worse.
