After 19:30, the Karaoglanoglu (Karaoğlanoğlu) coastal corridor shifts into evening rhythm. Restaurant traffic increases, curb-side activity becomes layered, and through movement toward Alsancak remains steady.

Within this rhythm, motorbike behaviour introduces a distinct exposure.

The risk does not originate from excessive speed. It forms from timing misalignment during short-distance overtakes.

Between 19:30 and 21:30, corridor density becomes uneven. Vehicles slow briefly for parking searches, pedestrian crossings, or right turns into seafront venues. These micro-slowdowns create temporary gaps ahead of moving traffic.

A recurring scenario develops.

A westbound vehicle reduces speed slightly due to a curb-side hesitation ahead. Behind it, a motorbike rider identifies an apparent opening and shifts toward the center line to overtake. At that moment, the leading vehicle begins braking more decisively for a pedestrian emerging between parked cars or for a sudden parking maneuver.

The motorbike is now positioned laterally, partially committed to the overtake, with reduced escape space.

The geometry of the corridor contributes subtly. The road appears straight and open, encouraging brief passing maneuvers. However, lateral unpredictability increases after sunset due to:

• Informal pedestrian crossings
• Sudden curb-side stops
• Vehicles merging from restaurant exits

The rider calculates forward distance correctly but underestimates lateral interference risk.

Lighting conditions reinforce the exposure. Artificial lighting from restaurants creates alternating bright and shadowed segments. Motorbike riders, whose visual perception relies heavily on contrast and lane clarity, may misjudge the exact braking intensity of the vehicle ahead when glare from illuminated storefronts reflects off car surfaces.

Season intensifies frequency. In summer months, motorbike usage increases due to tourism and recreational evening travel. In winter, frequency decreases but remains present during weekend dining peaks.

Historically, when the coastal strip functioned more as a connector and less as an evening destination axis, overtakes were primarily distance-based decisions. Today they are interruption-based reactions to micro-slowdowns.

The exposure is rarely high-speed collision. It is lateral instability created by overtaking within a corridor that behaves unpredictably after dark.

As long as short-distance overtakes occur in response to minor speed fluctuations within a destination-heavy evening strip, motorbike timing errors after 19:30 will remain a recurring pattern along Karaoglanoglu coastal corridor.
