Ronald was driving continuously without rest. Felix offered some help, but Ronald refused since he wanted to settle it with his own hand.
He knew the government was at fault right now, so he wanted to bring some justice to the wronged people.
While he was driving, Felix kept looking around to check whether people were following them or not.
Theo had told him about the tracker, so he believed they wouldn't go as far as following them.
At the very least, they knew Ronald wouldn't destroy the evidence. So, they could simply retrieve it and buy some time from Ronald before they published the evidence first.
This way, they could justify that Ronald had stolen the evidence.
They waited patiently as Ronald finally went off the road, indicating they were already close.
