I'm looking for feedback on what is the morally correct thing to do in both of these scenarios. What is the most fair and reasonable outcome?



Scenario 1: Fine and Points

Alex was caught speeding and asked bob for a favour to take his 3 points and says he will pay £60 fine and any increase in premium from the 3 points for the time they are on Bob's license.
Bob agreed to do favour.
Alex nominated Bob,
New notice was sent to Bob,
Alex kept asking if the notice had come yet and Bob kept saying no,
The time in which to pay before being summonsed passed and Bob then discovers letter he thought was bank statement, but just never bothered to open, was actually the notice, but it's already too late.
Bob goes to court and gets £150 fine instead of the £60 fine and 2 extra points, so 5 points total.
Because of Bobs mistake, Alex now has much higher cost for both the fine and the premium being more than double what it would have been had the fine been paid on time and it was only 3 points.

Cost to Alex without mistake:
£60 fine, £252 premium increase, TOTAL: £312

Cost to Alex with mistake:
£150 fine, £543 premium increase, TOTAL: £693

Cost of mistake: £381




Scenario 2: Oil

Alex is self employed with a job that involves driving.
Alex needed help one day and Bob was available so Bob drove Alex's work motor by himself.
Bob still had 100+ miles to drive before finishing for the day.
The oil light came on while Bob was driving.
Bob got out and checked the oil at the side of the road with the dipstick which indicated there was enough. Unknown as to whether it was on level ground and it most likely wasn't allowed cool before checking.
Bob made no effort to contact Alex to inform him the light was on or to ask what he wanted to do.
Bob continued to drive with the oil light on, for circa 100 miles.
The engine seized and the motor had to be towed to Alex's mechanic.
This cost Alex over £600 for a used engine and labour plus the time and money spent running around to get engine.


Any feedback at all would be great!
