Snakeybus Intersect 4590 (PC World Record; Last Route Cycle); More Information in the Description

See my pinned comment for relevant video links and to see route tweaks.

This is the last cycle of my route on Intersect for PC.

PREGAME MATH
For this run, I aimed to be about 2075 buses long before making the last major dropoff for the following reasons:
-To get a good amount of space away from my tail, which minimizes chances to get squeezed by my buses
-Maxing out on passengers at 2075 buses long makes it possible to become at least 5533 buses long; I didn’t expect to reach a length of 5533 due to the effects of lag but it’s good to have the potential length overshoot the expectations

To ensure I was about 2075 buses long first, I used the formula from my "Important PC Snakeybus Math Formula and How to Use It" video to figure out that I should be close to 291.8 buses long before dropping off the maximum number of passengers for the rest of the game. In this run, I was 291 buses long.

DROPOFF SKIP
At 0:22, go left of the dropoff to make a spiral on the ramp. Then at 0:52, jump out of the spiral and go left of the dropoff again.

ROUTE TIPS
*= helps with endgame plan
*At 0:57, land and stay on the left side of the ramp.
*At 1:00, go straight instead of cutting across to pick up the passengers. For early route cycles, it's fine to pick up these passengers.
*After the jump at 4:21, land close to the wall at 4:23.
-Switch to first person at 4:35 once you're by the last part of the wall on your right and at about 5:02 once you're comfortably going straight. Then at 4:36-4:47 and 5:03-5:13, pay attention to the bottom of the vertical window divider. Try to have the bottom of the divider be lined up with the edge of the pathway you drive on.
-At 4:51-4:57, drive along the pathway edge to ensure space on both sides of you for future parts of the route.
*At 5:14, stay against the wall and under your buses before driving into the next lane.
-At 7:54, refer to the lightened ground to make sure you don't drive off the edge.
-After driving through the lightened ground for the third time, be ready to jump at 8:09 as soon as your bus faces the other direction.
-At 8:46, pay attention the bus stop shelter on the ground below you to the right (this is the same one you drive past at 16:33). Jump as soon as this bus stop shelter is out of sight.
-At 12:52, drop down to the ramp on the left as soon as your bus is entirely in the lightened part of the pathway.
*At 12:55, land and stay on the left side of the ramp.
-At 13:03, be barely right of the bus stop shelter. As soon as you're past this bus stop shelter, turn left.
-At 13:23, drive left off the pathway as soon as your bus is entirely in the darkened part of the pathway.
-At 13:25-13:28, when you have your bus facing the correct direction, air roll left while holding the brakes to ensure space on both sides of you for future parts of the route.
-At 13:59, jump just before reaching the shadow edge.
-At 14:00-14:04, have the arc of the jump be very high to lessen the chance of air traffic with buses from the jump at 8:46.
-At 14:36, pay attention to the gap between the pathways on your right. Jump as soon as you're next to the pathway support at 14:39.
-At 16:09, hit the gas to help with making the jump to the cliff area.
*At 16:19-16:29, leave a lane of space to your right.
-At 16:50, refer to the lightened ground for the left turn.

ENDGAME PLAN
-At 19:15-19:22, drive on the left side of the ramp on your way to making the last major dropoff.
*I wasn't maxed out on passengers because I wanted to finish the run faster. Dropping off the passengers I had would result in a potential length that's just over mid 4000s (which is longer than I expected to reach due to the effects of lag).
-At 19:25-19:59, make a spiral on the ramp.
-At 20:03-22:40, make a spiral in the empty space.
-At 22:51-23:34, drive on the buses of the upcoming spiral.
-If possible, pick up passengers at 23:38 before going across the dropoff zone at 23:43.
-At 23:51 as soon as you drive over the passenger pick up zone, boost onto the buses you'll drive on.
-At 24:36, jump to the ground by the cliff edge.
-At 24:45-25:16, drive on the buses on the curved pathway.
-At 25:17, boost onto the buses. Land as much left as you can.
-At 25:19-27:11, drive on the buses going through the tunnel.
*If you end up falling to the right at 26:56, be aware that the sloped ground on the right at 27:00 can get you back on track.
-At 27:15, drop/boost to the right onto the ground buses.
-At 27:17-29:07, drive on this spiral of buses as much as possible.
*The last planned spiral drive for me went more chaotic than expected; the following timestamp link was more what I envisioned:    • Snakeybus Intersect 4284 (Former PC World ...  

FINAL NOTE
At 30:15, this run's score didn't show up on the leaderboard because the game developers set a cap of 3000 as a way to prevent hackers. As you can see, what I did is legitimate and to further show its legitimacy, I uploaded a video showing my 4590 PC run fully from start to finish.
