Blessing drove the car through one of the alleys to the other road, and then turned the car in the direction the kidnappers' bus was moving and headed down since the other road is also on a straight line. Blessing drove with speed on the other road so he could match the bus's speed, and Blessing was able to see the bus on the first road through the alleys that link the two roads together.
Ivy, Isa, Olivia, and Avy drive speedily behind the bus to make it seem to the kidnappers that they are on their tail. As instructed, Ivy, Isa, Olivia, and Avy did not try to overtake the bus or try anything funny but continued to follow the speedy bus.
In a common sense, one would know that the bus driver would have found out that Blessing's car was no longer behind them even though there is another following them. The other car that was also following the bus did not try to overtake the bus but continued to speedily follow the bus not to lose it.
