Missions not completable due to bad car allocation

I am trying to get through missions to get back mods again but I have the same mission with the older Brucknell keeps on skidding all the time and just crashes every single time. I have spent 3 hours on the same mission and getting nowhere. Now if one mission fails in career everything would be locked not just the two new ones & mods which is why I ended up stuck on the same mission on FH4. How do I complete this?

 

I have tried the same mission for over three hours, how am I supposed to just get it done?

This mission doesn't seem to even have objective I have followed the same car until it starts spinning then it fails as the other has disappeared, if I hit the other car it just changes location then continues. How am I supposed to access the last two cars without code?

 

I mean, the Moonhawk is notoriously boaty when it comes to handling, and I know the pain of driving them because I use a keyboard. I guess you just have to get better at driving.

 

which mission is it?

 

This is with East Coast Chase #1 which is classed as "Medium", however Electric Hypermiling is classed as "Hard" which is just driving normally from A to B where I finished with 3% charge still left in the battery from 5% at the start.
