This is true - there was an absolutely horrific case on the A1(M) in 2024 where a drunk driver was travelling at twice the speed limit and killed a baby and his aunt. The driver was jailed & received a long ban, but not a lifetime one. The victims’ mother / sister has a petition for lifetime bans in such cases.
With lesser driving offences, there’s also the problem of the exceptional hardship defence which can help drivers keep their licence - it’s easy to spot when you read local crime reports as the defendant’s lawyer will plead that they are a carer, will lose their job, are overcoming personal difficulties etc.
With the N Ireland case, the question is I think what should justice look like. Prison is a complicated issue with the lack of spaces & whether it works, & I can see why a judge might want to avoid sending an elderly woman of previous good character there. But the issue is that her driving did lead to someone’s death & what would be justice for the victim & her family who have lost a mother / grandmother? If the practical effect of a ban is that she will no longer be able to drive, why not just rule that? It feels a perfectly reasonable outcome, both in justice for the family and in protecting the public in future.
This is where I think reporting of road traffic collisions really isn’t adequate - if this type of incident happened on the railway, it would be headline news & there would be an enquiry. But on the roads, it’s normally just a piece in the local news with no investigation into what might have prevented the collision or examining how effective the legal process is.
