Why could only Logan take Laura to Eden?

In Logan (2017), Gabriela tracked down Logan and took his help in sending Laura to Eden, in the process getting killed by the Reavers/henchmen who tracked her down. Of course, she was aware of Laura's DNA connection to Logan, and it makes sense to expect that upon learning about this 'relation', Logan's protective instincts can kick in, and there can be no one better than the mythical Wolverine to safeguard Laura's journey to Eden.

It is great storytelling, but thinking about it afterwards, why did she need Logan for this in the first place, considering the following points:

• An early graveyard scene in the film shows that Gabriela had a light-blue/azul colored car, in which she drove past Logan, with Laura in the backseat. So, she had a car already.

• She offered Logan (plenty of) money to get this job done. So, she had ample amount of money too. So, even if she didn't have a car herself, she could've easily hired one for this long-distance journey.

• She knew the location/co-ordinates of the place they were heading to, and most importantly, the Reavers did not (initially). This is revealed later in the film, after the Munson family disaster, where one of the Reavers retrieves the photograph that Laura carries with her (with co-ordinates at the back). It is only after this that the Reavers start heading full-force towards Eden, beforehand they were only looking locally.

• She knew the Reavers were after them, so there had to be a sense of urgency about the escape. That shouldn't leave any time for convincing one-particular-driver-out-of-many-in-this-world for the journey. In fact, this whole find-Logan-convince-Logan scheme would be highly time consuming, for the Wolverine is mythically established to be a difficult, stubborn creature. And after all the time expenditure, there is always the possibility of Logan refusing. So, this proposition can also fail.

• She was very well conversant with Laura's adamantium claws and healing powers. So, if we leave out the Reavers/other Transigen henchmen, other mortal humans would not present any threat to her with Laura on her side, and the journey would be absolutely safe.

So, why couldn't she just take Laura along, either hop onto her car, or use the money to hire any other chauffeur-driven car, dump her phone, quickly escape the local area they started from, and then quietly head towards Eden on her own? The Reavers simply would not have any clue where to look for them.

Of course, this would completely ruin the emotional narrative Logan was intended to be, but isn't this a perfectly logically plausible line of thought? (Perhaps with this, Logan, Charles Xavier, Caliban, the Munsons, and Gabriela herself would all end up alive.)
