Cruise Control & Speed Limiter

Framework-agnostic cruise control that holds a set speed plus an adjustable max-speed limiter for highway and convoy driving.

NON-TESTÉ — the reference Lua is syntax-validated, not run in a live FiveM server. Adapt and test on your own dev server before shipping.

Description

Cruise control that locks the vehicle to its current speed (re-arming when you tap throttle or brake) plus an adjustable max-speed limiter for highways and convoys. The selling point is the smoothness — naive implementations jitter, so a clean speed-hold is what servers actually pay for.

Known Failure Modes & Corrective Prompt

  • Jitter — forcing SetVehicleForwardSpeed every frame fights physics; yield to live throttle/brake input and re-arm.
  • Unit mismatch — comparing km/h against m/s clamps at the wrong speed; standardize on m/s.
  • Passenger cruise — guard the hold loop with the driver-seat check.

Corrective re-prompt: "Cruise control jitters and the limiter caps at the wrong speed. Re-arm the target speed whenever control 71 or 72 is pressed (don't force speed then), and convert the limiter from km/h to m/s with /3.6 before comparing to GetEntitySpeed, which is m/s."

Framework Integration

  • ESX: show the cruise/limiter state with ESX.ShowNotification after exports['es_extended']:getSharedObject().
  • QBCore: QBCore.Functions.Notify from exports['qb-core']:GetCoreObject().
  • QBox: exports.qbx_core:Notify; works unchanged on qbx since it is native-driven.

Profit Potential

$150–$2000/mo on Tebex (expected ~$550). [INFERRED] $50-389 script band (§2) × estimated units/mo for a stable niche, benchmarked against the signal-scraper tebex_snapshot corpus (n=100, median seller $11.85K/mo).

Trend Signal

→ stable — inferred: Cruise + speed-limiter is a steady QoL ask (smooth speed-hold logic is the work); modest but durable standalone demand.

Sales Angle

Target trucking, convoy, and long-haul RP servers where a steady speed is a real need, and lead with the smooth-hold logic as the differentiator. Recommended Tebex price: $80.
